摘要

Abstract Li(sec-Bu)3BH-mediated reductive cyclization of optically pure 8-((S)-p-tolylsulfinyl)-(2E,7Z)-octadienoate 9 and 7-(p-tolylsulfinyl)-2,6-heptadienoate 16 afforded trans-2-((p-tolylsulfinyl)-methyl)cyclohexane-1-carboxylate and trans-2-((p-tolylsulfinyl)methyl)cyclopentane-1-carboxylate, respectively, as a single isomer. © 1997 Elsevier Science Ltd.
