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.

A chemoenzymatic dynamickineticresolution (DKR) of N‐heterocyclic amino alcohols is described. Various lipases were studied as biocatalysts for the kineticresolution of N‐heterocyclic 1,2‐amino alcohols. The influence of the support of the enzymes on the enantioselectivity in the resolution of different substrates is highlighted. Various 3‐acetoxypyrrolidines and ‐piperidines were obtained in high

Aryl fluorosulfonates are developed as a deoxyfluorinating reagent in the transformation of primary and secondary alcohols into the corresponding alkyl fluorides. These reagents feature easy availability, low-cost, high stability and high efficiency. Diverse functionalities including aldehyde, ketone, ester, halogen, nitro, alkene, and alkyne are well tolerated under mild reaction conditions.
