Synthesis of 3,4-Di-O-benzyl-1-O-methyl-L-galactitol, a key precursor of the C33-C37 fragment of calyculins
3,4-Di-O-benzyl-1-O-methyl-L-galactitol (3) has been synthesized in a seven step sequence starting from 1,2:3,4-di-O-isopropylidene-alpha-D-galactopyranose (4). The synthesis involves the methyllation of HO-6 of 4, followed by methanolysis to the mixture of the corresponding methyl 6-O-methyl-alpha-...
