The synthetic idea relies on the construction of two rings (beta-lactone and pyrrolidinone). The formation of the spiro-beta-lactone was accomplished by a crossed Cannizzaro reaction, while the 3,4-disubstituted pyrrolidinone ring was constructed by a titanium(IV) chloride mediated chelation-controlled double stereodifferentiating Crimmins aldol reaction of Garner's aldehyde.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">19</style></issue><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">2.260</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%">Kumar, Manish</style></author><author><style face="normal" font="default" size="100%">Kumar, Pawan</style></author><author><style face="normal" font="default" size="100%">Das, Utpal</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Photocatalytic oxidation of α-substituted amines to lactams/amides</style></title><secondary-title><style face="normal" font="default" size="100%">Advanced Synthesis &amp; Catalysis</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">alpha-Aminonitriles</style></keyword><keyword><style  face="normal" font="default" size="100%">Decyanation</style></keyword><keyword><style  face="normal" font="default" size="100%">Dioxetanimine</style></keyword><keyword><style  face="normal" font="default" size="100%">Photocatalytic</style></keyword><keyword><style  face="normal" font="default" size="100%">pyrrolidine</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2025</style></year><pub-dates><date><style  face="normal" font="default" size="100%">FEB </style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">367</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;
	We, herein, report a base free, photocatalytic decyanation of alpha-aminonitriles. A range of amides and lactams were obtained in 52-95% yields. Control experiments indicate O2 as an amide/lactam oxygen source and the reaction (lactam formation) follows radical pathway via dioxetanimine species. This methodology also applied for alpha-ester/aldehyde substituted pyrrolidines in the presence of a base, probably via decarboxylation pathway.&lt;/p&gt;
