The Heck, Stille, or Suzuki coupling reactions of two different electron-rich phenolic segments bearing geranylated or farnesylated units were involved in the decisive step. The Sonogashira coupling reaction followed by palladium-catalyzed chemo-and stereoselective cis-reduction of an alkyne unit and subsequent isomerization to give the desired natural products is also described.</p>10ageranylated or farnesylated stilbenes10aNatural products10apalladium-catalyzed coupling reactions10aphloroglucinol10aTotal synthesis1 aSingh, Mandeep1 aArgade, N., P.  uhttps://library.ncl.res.in/content/palladium-catalyzed-routes-geranylated-or-farnesylated-phenolic-stilbenes-synthesis-001121nas a2200157   4500008004100000022001400041245014000055210006900195260007100264300001000335490000700345520043900352100002200791700001900813856013100832       2013                        eng d  a1523-706000aPalladium-promoted [2+2+2] cocyclization of arynes and unsymmetrical conjugated dienes: synthesis of justicidin B and retrojusticidin B0 aPalladiumpromoted 222 cocyclization of arynes and unsymmetrical   a1155 16TH ST, NW, WASHINGTON, DC 20036 USAbAMER CHEMICAL SOCcJAN  a14-170 v153 a<p>A facile synthesis of natural and unnatural arylnaphthalenes has been demonstrated via the unprecedented palladium-promoted [2 + 2 + 2] cocyclization of arynes and unsymmetrical conjugated dienes using the N-heterocyclic carbene as a ligand.
