- Stereoelectronic effects and chiral recognition, II: Kinetic and thermodynamic control in the formation of chiral thioacetals and chiral thioethers
-
The ratio of diastereomers obtained from chiral thiols 2 was shown to be time-dependent both in thioacetal formation with lactol 1 (diastereomers 3/4) and in 1,4-addition to nitrostyrene 5 (diastereomers 6/7, 8/9). An interpretation based on stereoelectronic effects is presented to explain the similarity of the reaction pathways in both reactions. VCH Verlagsgesellschaft mbH, 1996.

- Direct Conversion of Alcohols into Thiols
-
A simple one-pot reaction between alcohols and 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane 2,4-disulfide (Lawesson's reagent, LR) affords the corresponding thiols, accompanied by dehydration products, alkenes.Treatment of acyclic 1,4-diols with LR gives the 1,3-dienes. o-(Dihydroxymethyl)benzene derivatives yield the 1,3-dihydrobenzothiophenes when treated with LR.
