摘要

Abstract The title compounds, readily prepared by the reaction of the corresponding S- methyl N-(p-toluene-sulfonyl) dithioiminocarbonate and 2-mercaptothiazoline with (chloromethyl) trimethylsilane in the presence of a base, were used as new reagents for the introduction of a thioformaldehyde unit to a carbonyl carbon. The reaction of these compounds with aldehydes in the presence of cesium fluoride afforded thiiranes via the 1, ...
