Stereoselective syntheses of 1,2-dialkyl-1-phenyl cyclopentanes involving intramolecular carbolithiation of α-thioalkenes

2-Ethyl-1-methyl-1-phenyl cyclopentane, unavailable by butyllithium-promoted carbocyclisation of the corresponding alkenyl selenide, has been synthesized from 6-methylseleno-6-phenyl-1-phenylthio-1-heptene and 7-methylseleno-7-phenyl-2-phenylthio-2-octene with high stereocontrol at all the three stereogenic centers. Depending upon the solvent used, the derivative in which the methyl- and the phenylthiomethyl groups are cis (in THF) or trans (in pentane) to each other are formed selectively.

Thiol Esters from Sulfoxides via Rearrangement of Sulfoxide Phosphines to Sulfide Phosphine Oxides

Treatment of α-lithio sulfoxides with (1) ClP-(C6H5)2 and (2) I2 (isolate sulfide phosphine oxide 3) followed by (3) C4H9Li and (4) O2 affords thiol esters.
