supporting information; experimental part, p. 3752 - 3755 (2012/09/07)
A modular stereoselective synthesis of the vesicular monoamine transport inhibitors (+)-tetrabenazine ((+)-1) and (+)-α-dihydrotetrabenazine ((+)-2) has been developed. The approach is based on amine 4 and acid 5 as the key building blocks, which were elaborated into macrolactam 3 by amide coupling and a subsequent highly E-selective RCM reaction. Macrolactam 3 could be converted into tetrabenazine in three known steps.
Application of the ortho-Lithiation-Cyclization Strategy to N-Benzyl- and N-Phenethylamine Derivatives

The ortho-lithiation-cyclization of iodinated N,N-diacylphenethylamines provides a convenient method for the preparation of 2-(2-acetoamidoethyl)acetophenones and 2-(2-benzamidoethyl)benzophenones, which could be easily transformed into dihydroisoquinolines.By contrast, the N-ethylamino, N-acetylamino, and N-trimethylsilylamino moieties studied as ortho-directing groups provide poor assistance to the metalation of N-benzyl- and N-phenyethylamines and the corresponding isoindolone or isoquinolone derivatives are obtained in low yields.
