Construction of anti-1,2-diols bearing chiral tertiary alcohol moiety using free hydroxyacetone as aldol donor by imidazole-based prolineamide catalyst
摘要:
A direct aldol reaction of free hydroxyacetone and activated ketone has been firstly achieved with a newly developed imidazole-based prolineamide catalyst. The adducts anti-1,2-diols bearing a chiral tertiary alcohol moiety were obtained in high yield (up to 92%) and stereoselectivity (up to 15:1 dr and 90% ee). (C) 2014 Published by Elsevier Ltd.
