  Highly Enantioselective Direct syn- and anti-Aldol Reactions of Dihydroxyacetones Catalyzed by Chiral Primary Amine Catalysts

  摘要：

  We present herein simple primary-tertiary diamine-Bronsted acid conjugates that catalyze both syn- and anti-adol reactions of dihydroxyacetones (DHAs) with high diastereoselectivities and enantioselectivities. This type of organocatalysts functionally mimics all four DHA aldolases, namely L-fuculose-1-phosphate aldolase, D-tagatose-1,6-diphosphate aldolase, D-fructose-1,6-diphosphate aldolase, and L-rhamnulose-1-phosphate aldolase.

• Proline–cyclodextrin conjugates: synthesis and evaluation as catalysts for aldol reaction in water

  The synthesis of six conjugates of L-proline and beta-cyclodextrin and their evaluation as catalysts of aldol reaction in water are described. The results indicated that the nature of the linker between proline and beta-cyclodextrin is important for catalytic activity: the one with the most flexible linker gave the best results. Inhibition experiments showed that the cavity of beta-cyclodextrin plays a role in the catalysis. Permethylation of the cyclodextrin hydroxyl groups led to higher conversion rates.
