, p. 17 - 20 (1994)
The hydroxyamino acid moiety of AI-77-B has been prepared from D-ribose in an optically pure form via stereoselective alkylation of N-acylpyrrolidinium ion intermediates as the key step.

We have developed a practical synthesis of the chiral lactam as a new chiral building block for alkaloid synthesis. Lipase-catalyzed kinetic resolution of hydroxylactam 8, followed by isolation-racemization of the chiral acetoxylactam 9 provided the optic

(formula presented) An enantioselective total synthesis of Al-77-B (1), a gastroprotective substance isolated from a culture broth of Bacillus pumilus Al-77, was performed in high overall yield. In this synthesis, the dihydroisocoumarin part 14 and the di
