摘要
: The seco-acid derivative 7, which has the 9,11-and 3,5-diols protected as the mesityl- and 3,4-dimeth-oxypheny- (DMP) acetals, respectively, was stereoselectively synthesized from D-glucose and converted to Yam-aguchi's mixed anhydride, which was treated with a high concentration of DMAP at room temperature to rapidly give the 14-membered lactone in 98% yield. Removal of the protecting groups gave 9-dihydroerythronolide A. © 1990, American Chemical Society. All rights reserved.
