Chiral dienophiles l-3 undergo highly exo and diasfereoface selective Die/s-Alder reactions. The Die/s-Alder reactions of 3 are also highly exo selective under Lewis acid catalyzed conditions. In connection with an ongoing effort in the natural products arena we required a highly diastereoselective

Lithium enolates derived from the title esters show high diastereoface selectivity in their reactions with chiral aldehydes. The resulting 2,2-dithioaldols are desulfurized in good yield with Ni28-H2 (EtOH, 20ยฐC). With this mild desulfurization protocol, complete retention of stereochemical integrit
