Abstract

An attempt at an asymmetric Pummerer-type reaction of trans-4-benzyloxythiane-1-oxide (1) with 3-trifluoroacetyl-4S-isopropyl-1, 3-thiazolidine-2-thione (2) resulted in failure but an attractive desulfurilative self-coupling reaction of 4S-isopropyl-1, 3-thiazolidine-2-thione (6) occurred to give 4S-isopropyl-3-(4S-isopropyl-1, 3-thiazolin-2-yl)-1, 3-thiazolidine-2-thione (5). The same desulfurilative self-coupling reaction of compound 6 or 11 efficiently ...
