The Pd-catalyzed asymmetric addition reaction of solid phase-supported alcohol with ene-alkoxyallenes is reported. Combined with the subsequent metal catalysis, this reaction gave access to various monosaccharides with no need for isolation of the intermediates. Potential utility of the method in the oligosaccharide synthesis was demonstrated by the synthesis of (α)-mannose disaccharide.
