The synthesis of (+)-trans-2-mercaptocyclohexanol and (-)-trans-2-mercaptocyclohexanol was described. Ring opening of cyclohexene oxide with (-)-4-methoxybenzyl-3(R)-nopanethiol followed by oxidn. gives two readily separable diastereomeric sulfoxides

The allylic sulphoxides1b and1e reacted with 1-pyrrolidinylcyclohexene and 2-ethoxycarbonyl cyclopentanone to yield the 2-substituted keto-sulphoxides10 and14 respectively, which on reduction followed by oxidation yielded in each case a mixture ofcis

A short, stereoselective synthesis of estradiol, and its 6,6-dimethyl analogue, was accomplished from non-steroidal starting materials. A key feature was the use of a benzo[b]thiophene unit to effect (i) the stereoselective formation of the required

Enantiopure 1-methoxy-3-(1-phenyl- and 2-phenyl-2-hydroxyethylsulfinyl)-1,3-butadienes were prepared from ethyl mandelate. Diels-Alder reactions with methyl acrylate proceeded with complete regioselectivity and high diastereoselectivity.

Anionic species formed by treatment of vinyl sulfones with hydridoaluminates were trapped intramolecularly by esters to provide six- and seven-membered cyclic ketosulfones, e.g. I (R = Me, H, Ar = p-tolyl) and II, exemplified by the stereoselective c
