摘要
6-Methylseleno-6-phenyl-1-phenyithio-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 and methyl iodide or methanol respectively. Depending upon the solvent used, the derivative in which the methyl- and the phenylthio group are cis (THF) or trans (pentane) one to the other are selectively formed.
