(2S,3S,4S,5R)-2,3:4,6-Bis(isopropylidenedioxy)-5-[[(p-methoxybenzyloxy)carbonyl]amino]hexan-1-ol (14), a synthetic intermediate for (+)-galactostatin (1), has been synthesized starting from (+)-diethyl tartarate using the aldol-type condensation of methyl isocyanoacetate (2) with 4-O-benzyl-2,3-O-isopropyliden-L-threose (4) via a 3,4,5,6-tetrahydroxynorleucine derivative (8) as a key reaction.
