Total synthesis of (+)-azimine via diastereoselective aminopalladation

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.
