  Stereoselecnve total synthesis of (±)-tetraponerine-8

  摘要：

  A stereocontrolled total synthesis of the ant alkaloid (+/-)-tetraponerine-8 (1) has been achieved in 7 steps and 28% overall yield, starting from 1-hydroxypiperidine. Key steps are a 1,3-dipolar cycloaddition (3 + 4 -> 5), a nucleophilic substitution (14 -> 15), and a reductive cyclization affording the tricyclic skeleton of tetraponerine-8 (15 -> 17).

• A New Synthesis of All Four Stereoisomers of 2-(2,3-Dihydroxypropyl)piperidine via Iterative Asymmetric Dihydroxylation To Cause Enantiomeric Enhancement. Application to Asymmetric Synthesis of Naturally Occurring Piperidine-Related Alkaloids

  日期：1999.11.1

  Both enantiomers of 2-(2-propenyl)piperidine 1 (76-88% ee), prepared via the first asymmetric dihydroxylation (AD) of 5-hexenyl azide, underwent the second AD to provide all four of the stereoisomeric 2-(2,3-dihydroxypropyl)piperidines 2 with enantiomeric enhancement (>98% ee). An asymmetric synthesis, starting from 2, of several 2-(2-hydroxyalkyl)piperidine alkaloids [(-)-halosaline, (+)-N-methylallosedridine, (+)-8-ethylnorlobelol, (+)-sedridine, (+)-allosedridine, (-)-allosedridine, and (+)-N-methylsedridine] and the ant defense alkaloids [(+)-tetraponerine-3 (T-3), T-4, T-7, and T-8] is demonstrated.
