中文摘要：
有 acetylacetone 的 imine 的 Mannich 反应被修改 chiral 辛可宁有效地催化导出碱的 thiourea。反应导致了氨基的羰基在高收益和好 enantioselectivities 加重的 chiral。学习第一次证明有从 benzothiazole 导出的杂环的 imine 的未修改的 acetylacetone 的 Mannich 反应能被 chiral bifunctional organocatalyst 支持。
英文摘要：
Mannich reactions of imine with acetylacetone were effectively catalyzed by the modified chiral cinchona alka-loid-derived thiourea. The reactions led to chiral r-amino carbonyl compounds in high yields and good enantiose-lectivities. The study demonstrated for the first time that Mannich reactions of unmodified acetylacetone with het-erocyclic imine derived from benzothiazole can be promoted by chiral bifunctional organocatalyst.
