VERSATILE RELATIVE AND ABSOLUTE STEREOCONTROL IN STANNOUS TRIFLATE MEDIATED ALDOL-TYPE REACTIONS OF 3-(2-BENZYLOXYACETYL)THIAZOLIDINE-2-THIONE

Abstract
In the stannous triflate mediated aldol-type reactions of 3-(2-benzyloxyacetyl)thiazolidine-2-thione, stereochemical course of the reactions is dramatically altered by the addition of tetramethylethylenediamine as a ligand. High asymmetric induction is also achieved by the addition of chiral diamine derived from L-prolin.
