Chemistry of the microbial metabolite A88696F, a new 2-(α-hydroxyalkyl) tetronic acid
摘要:
Some unusual chemistry of the gastric ATP-ase inhibitor A88696F (3), a naturally-occurring 2-(alpha-hydroxyalkyl) tetronic acid, is described. It undergoes triethylamine-mediated reduction of the hydroxyl group to afford A88696C (1), presumably via the olefin 4. This olefin was prepared from 3 in high yield under mild acidic conditions, and was stereoselectively rehydrated bade to alcohol 3, and epoxidized to A88696D (2).
