Daucus carota Mediated-Reduction of Cyclic 3-Oxo-amines
摘要:
Carrots (Daucus carota) were used to reduce cyclic amino-ketones in high yields and enantiomeric excesses. This cheap, eco-compatible, and efficient reducing reagent allows the easy access to precursors of biologically active products.

Abstract The asymmetric benzylation of methyl 4-oxo-3-piperidinecarboxylate has been investigated, and methyl (R)-1,3-dibenzyl-4-oxopiperidine-3-carboxylate (3c) was obtained by using a phase-transfercatalyst O-allyl-N-9-anthracenemethyl-cindexnine bromide (1k). This synthetic method has the advantages of cheap materials, mild reaction conditions and moderate enantioselectivity, and is useful for
