Construction of all O-alkoxy D-tetrose and D-pentose stereoisomers from 2,3-O-isopropylidene-D-glyceraldehyde using 2-(trimethylsilyl)thiazole as a formyl anion equivalent

All D-tetroses and D-pentoses having differentially protected hydroxy groups are synthesized by an iterative one-carbon chain-elongation cycle commencing with the addition of 2-(trimethylsilyl)thiazole to 2,3-O-isopropylidene-D-glyceraldehyde. One half of
