An efficient synthetic method for the preparation of multisubstituted furans, thiophenes, and pyrroles using ynolates was developed. This novel formal [4 + 1] annulation by C2-C3 and C3-C4 bond formations Includes cycloaddition, cyclization, decarboxylati

The reaction of a series of 2,5-dihydrothiophenes with benzyne, generated from 2-carboxybenzenediazonium chloride, affords 1-phenylthio-1,3-dienes in good yields through the fragmentation of sulfonium ylide intermediates.
GENERAL SYNTHESIS OF POLYSUBSTITUTED THIOPHENES FROM DIKETO SULFIDES
Nakayama, Juzo,Machida, Haruki,Saito, Ryuji,Hoshino, Masamatsu
, p. 1983 - 1984 (2007/10/02)
Treatment of diketo sulfides with a low-valent titanium reagent at 0 deg C (in two cases at room temperature) affords 3,4-dihydroxythiolanes in good yields.The acid-catalyzed (p-toluenesulfonic acid) dehydration of the latter compounds leads to the corres
