  描述：

  N-(2,2,2-trifluoroethyl)pyrazine-2-carboxamide 在 palladium dihydroxide 氢气 、 (+)-10-camphorsulfonic acid 、 三乙胺 作用下， 以 乙醇 、 醋酸异丙酯 、 水 、 乙腈 为溶剂， 10.0~90.0 ℃ 、275.79 kPa 条件下， 反应 76.5h， 生成 tert-butyl (3S)-4-{(2S,4R)-4-benzyl-5-[(3aS,9bS)-2,2-dimethyl-3a,9b-dihydro-2H-chromeno[4,3-d][1,3]oxazol-1(4H)-yl]-2-hydroxy-5-oxopentyl}-3-{[(2,2,2-trifluoroethyl)amino]carbonyl}piperazine-1-carboxylate

  Total synthesis of a second generation HIV protease inhibitor

  摘要：

  An efficient stereoselective preparation of HIV protease inhibitor (+)-1 was synthesized on multi-kilogram scale in 16 steps without the use of chromatography. The key steps include the diastereoselective alkylation of acetal 3, a diastereoselective iodo-hydroxylation to generate epoxide 6, and a reductive amination in the final coupling step that averts a non-productive Cyclic aminal intermediate.
