摘要

The bromolactonization of the optically active acetals derived from 2-acetyl-5, 8-dimethoxy- 3, 4-dihydronaphthalene and (R, R)-N, N: N′, N′-tetraalkyltartaramide was found to proceed highly diastereoselectively, giving mixtures of the seven-membered bromo lactones and the bromohydrins. The predominantly produced bromo lactones could be effectively converted to (R)-2-acetyl-5, 8-dimethoxy-1, 2, 3, 4-tetrahydro-2-naphthol, the AB ring ...
