An optimised and recoverable tartrate surrogate for sharpless asymmetric epoxidations
摘要:
The tetrahydroxy diester 7d (R = Pr-i) is almost as effective as diisopropyl tartrate in SAE reactions of (E)-allylic alcohols and can be recovered and re-used following a relatively simple work-LIP procedure. (C) 2008 Elsevier Ltd. All rights reserved.
