The Lewis acid mediated reaction of carbamates with γ-oxygenated allyltin and its application to (±)-statine synthesis
Abstract
The Lewis acid mediated reaction of acyliminium ions (6) with γ-oxygen substituted allyltin (1c) gave the amino alcohol derivatives (7) and/or (8) in good yields; in certain cases very high diastereoselectivity was achieved and the procedure was applied to the synthesis of (±)-statine.
