Diels-Alder addition with the silyl ether of buta-1,3-dien-l-ol in the presence of DDQ to yield the fused-phenol derivative (51), which was further modified by standard reactions.A bicyclosugar derivative (52) arises by Dieckmann cyclization of the branched-chain sugar diester (53) in the presence of 18-crown-6, the enolized form of the isomeric B-ketoester (54) is the only product, obtained in low yield (Scheme 11). 8... [Pg.150]
