The trifluoroacetic acid salt of 2-(pyrrolidinylmethyl)pyrrolidine was found to be an effective organocatalyst of an asymmetric intramolecular aldol reaction, affording bicyclo[4.3.0]nonane derivatives with a high enantioselectivity, in which the rare combination of aldehyde as a nucleophile and ketone as an electrophile was realized.
发现2-(吡咯烷基甲基)吡咯烷的三氟乙酸盐是不对称分子内醇醛反应的有效有机催化剂,提供具有高对映选择性的双环[4.3.0]壬烷衍生物,其中稀少的醛作为亲核试剂和酮已成为亲电子试剂。
