Stereoselective syntheses of 1,2-dialkyl-1-phenyl-cyclopentanes by intramolecular carbolithiation of vinyl sulfides

, 1995
6-Methylseleno-6-phenyl-1-phenylthio-1-heptene and 7-methylseleno-7-phenyl-2-phenylthio-2-octene produce 1-phenyl-2-(1'-phenylthioethyl)-cyclopentanes with high stereocontrol at all the three stereogenic centers on sequential reaction with butyllithium ...
