Synthesis and isolation of aryl thioaldehyde S-oxides
Abstract
(E)-Phenyl and (E)-(p-tolyl) trimethylsilyl thioketone S-oxides can be easily and stereospecifically protodesilylated into the corresponding (Z)-aryl thioaldehyde S-oxides; these stable liquid lachrimatory compounds show good reactivity as heterodienophiles and the reaction with 1,3-dienes is surprisingly non-stereospecific.
