In this context, an efficient transition-metal-free process has been demonstrated, wherein a broad range of alkyl/aryl/heteroaryl sodium sulfinates react with varyingly substituted aryne precursors (o-silyl aryl triflates) under mild reaction conditions to afford structurally diverse sulfones in good to excellent yields.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">14</style></issue><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">2.17</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Franke, Jana</style></author><author><style face="normal" font="default" size="100%">Bock, Martin</style></author><author><style face="normal" font="default" size="100%">Dehn, Richard</style></author><author><style face="normal" font="default" size="100%">Fohrer, Joerg</style></author><author><style face="normal" font="default" size="100%">Mhaske, Santosh B.</style></author><author><style face="normal" font="default" size="100%">Migliorini, Antonella</style></author><author><style face="normal" font="default" size="100%">Kanakis, Argyrios A.</style></author><author><style face="normal" font="default" size="100%">Jansen, Rolf</style></author><author><style face="normal" font="default" size="100%">Herrmann, Jennifer</style></author><author><style face="normal" font="default" size="100%">Mueller, Rolf</style></author><author><style face="normal" font="default" size="100%">Kirschning, Andreas</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Total and semi-syntheses of antimicrobial thuggacin derivatives</style></title><secondary-title><style face="normal" font="default" size="100%">Chemistry-A European Journal</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">antibiotics</style></keyword><keyword><style  face="normal" font="default" size="100%">lactones</style></keyword><keyword><style  face="normal" font="default" size="100%">Natural products</style></keyword><keyword><style  face="normal" font="default" size="100%">synthesis design</style></keyword><keyword><style  face="normal" font="default" size="100%">Total synthesis</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2015</style></year><pub-dates><date><style  face="normal" font="default" size="100%">MAR</style></date></pub-dates></dates><number><style face="normal" font="default" size="100%">11</style></number><publisher><style face="normal" font="default" size="100%">WILEY-V C H VERLAG GMBH</style></publisher><pub-location><style face="normal" font="default" size="100%">BOSCHSTRASSE 12, D-69469 WEINHEIM, GERMANY</style></pub-location><volume><style face="normal" font="default" size="100%">21</style></volume><pages><style face="normal" font="default" size="100%">4272-4284</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;The total and semi-synthesis of 13 new macrolactones derived from thuggacin, which is a secondary metabolite from the myxobacterium Sorangium cellulosum, are reported. The thuggacins have attracted much attention due to their strong antibacterial activity, particularly towards Mycobacterium tuberculosis. This study focuses on 1) thuggacin derivatives that cannot equilibrate by transacylation between the three natural thuggacins A-C, 2) the roles of the thiazole ring, and 3) the hexyl side chain at C2. Semi-synthetic O-methylation at C17 suppressed the transacylations without a substantial loss of antibacterial activity. Exchanging the C17-C25 side chain for simplified hydrophobic chains led to complete loss of antibacterial activity. Exchange of the thiazole by an oxazole ring or removal of the hexyl side chain at C2 had no substantial effect on the biological properties.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">11</style></issue><custom3><style face="normal" font="default" size="100%">&lt;p&gt;Foreign&lt;/p&gt;</style></custom3><custom4><style face="normal" font="default" size="100%">5.771</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Dhokale, Ranjeet A.</style></author><author><style face="normal" font="default" size="100%">Mhaske, Santosh B.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Transition-metal-catalyzed reactions involving arynes</style></title><secondary-title><style face="normal" font="default" size="100%">Synthesis-Stuttgart</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">annulation</style></keyword><keyword><style  face="normal" font="default" size="100%">arynes</style></keyword><keyword><style  face="normal" font="default" size="100%">Cycloaddition</style></keyword><keyword><style  face="normal" font="default" size="100%">Insertion</style></keyword><keyword><style  face="normal" font="default" size="100%">multicomponent</style></keyword><keyword><style  face="normal" font="default" size="100%">Natural products</style></keyword><keyword><style  face="normal" font="default" size="100%">Transition Metal</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2018</style></year><pub-dates><date><style  face="normal" font="default" size="100%">JAN</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">50</style></volume><pages><style face="normal" font="default" size="100%">1-16</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;The plethora of transformations attainable by the transition-metal-catalyzed reactions of arynes has found immense contemporary interest in the scientific community. This review highlights the scope and importance of transition-metal-catalyzed aryne reactions in the field of synthetic organic chemistry reported to date. It covers transformations achieved by the combination of arynes and various transition metals, which provide a facile access to a biaryl motif, fused polycyclic aromatic compounds, different novel carbocycles, various heterocycles, and complex natural products. 1 Introduction 2 Insertion of Arynes 3 Annulation of Arynes 4 Cycloaddition of Arynes 5 Multicomponent Reactions of Arynes 6 Miscellaneous Reactions of Arynes 7 Total Synthesis of Natural Products Using Arynes 8 Conclusion&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><work-type><style face="normal" font="default" size="100%">Article</style></work-type><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">2.650</style></custom4></record></records></xml>
