An l-proline-based β-amino tertiary thiol: synthesis and use as a catalyst in the enantioselective addition of diethylzinc to aldehydes
摘要:
Two independent routes for the synthesis of the novel beta-amino tertiary thiol 1 have been developed. Utilisation of this thiol in the enantioselective addition of diethylzinc to aldehydes provided (R)-secondary alcohols in ees of up to 64%. (C) 1999 Elsevier Science Ltd. All rights reserved.
