  A Convenient Method for Synthesis of Optically Active Methylphenidate from N-Methoxycarbonylpiperidine by Utilizing Electrochemical Oxidation and Evans Aldol-type Reaction

  摘要：

  A new method to prepare optically active methylphenidate starting from piperidine is described. The method consists of a transformation of N-methoxycarbonylated piperidine to the corresponding alpha-methoxylated carbamate utilizing electrochemical oxidation followed by the coupling reaction with optically active Evans imides to produce optically active methylphenidate derivatives with high stereoselectivity (erythrolthreo=5.3/94.7, the three isomer; 99.6%ee).

  Direct asymmetric α-chlorination of aryl acetic acid derivatives was achieved with a novel trinary activation system consisting of a catalytic amount of NiCl2/(R)-BINAP, Et3SiOTf, and a tertiary amine base. The reaction smoothly afforded the chlorinated compound in good yield with up to 89 % ee. Application of this reaction to a less acidic crotonic acid derivative gave the β,γ-unsaturated α-chlorinated

  An atom-efficient and green synthetic route to highly valuable imides (54–92% yields) from terminal alkynes and amides has been developed. This new route is composed of two consecutive reactions, that is, (i) the reported Cu(OH)2-catalyzed cross-coupling of terminal alkynes and amides to ynamides and (ii) the Sn–W mixed oxide-catalyzed regioselective hydration of ynamides.
