✦ Synopsis

The preparation of highly substituted J-hydroxy carbonyl compounds from isoxazolines is featured in a synthesis of crispatic acid. A J-hydroxy imine, the proposed intermediate in this transformation, is isolated for the first time and a stereoselective hydroboration of a 5-vinyl substituted isoxazoline is also reported.
