Enantiospecific total synthesis of the enantiomer of the indole alkaloid affinisine

The enantiomer of affinisine has been synthesized (from L-tryptophan) with 100% diastereoselectivity via the asymmetric Pictet-Spengler reaction coupled with a Pd°(enolate mediated) coupling process. This enantiomer has also been converted into a key inte

The Nb-benzyl group (see 7) has been employed in the Pictet-Spengler reaction in refluxing benzene to provide complete retention of optical activity in this process.The tetrahydro-β-carbolines 3b (trans) and 4b (cis) were independently converte
