The aminopalladation of amino allylic alcohol using Cl2Pd(MeCN)(2) in CH2Cl2 gave the 2,6-disubstituted piperidine with excellent diastereoselectivity. This compound was successfully converted into (+)-azimine (1) using cross-metathesis and Shiina macrolactonization. (C) 2013 Elsevier Ltd. All rights reserved.

text] The enantioselective total syntheses of (+)-azimine and (+)-carpaine have been developed, starting with (S)-1,2,4-butanetriol as a single source of chirality. The key common feature in these syntheses involves stereoselective intramolecular hetero-Diels-Alder reaction of an acylnitroso compound. The critical macrocyclic dilactonization of the N-Cbz derivatives of azimic acid and carpamic acid
