Rationally designed 4-phenoxy substituted prolinamide phenols organocatalyst for the direct aldol reaction in water
摘要:
A rationally designed 4-phenoxy Substituted prolinamide phenols as an efficient hydrophobic organocatalyst for direct asymmetric aldol reaction in water has been developed. High yield (up to 99%), diastereo-selectivity (up to 99:1), and enantioselectivity (up to 97%.) were obtained under optimal condition. The influence of substituent groups on the reactivity of catalysts was Studied in detail. Crown Copyright (C) 2008 Published by Elsevier Ltd. All rights reserved.
