The reaction of Garner's aldehyde with dithioacetate enethiolates followed by alkylation of the intermediate aldolate gives hydroxy-ketenedithioacetals with a moderate anti selectivity. This methodology was applied to the synthesis of various other ketene dithioacetals with high E or Z stereoselectivity.
