摘要
Asymmetric hydroformylation of crotononitrile (1) and ally cyanide (2) was probed with the view to develop a synthesis for (R)-4-amino-2-methyl-butan-1-ol. Hydroformylation of 1 under a variety of conditions mainly led to hydrogenated product. Hydroformylation of 2 with Rh/tris(2,4-di-tert-butylphenyl) phosphite gave good selectivity to the formylated nitrile with an n/iso of 77:23. Asymmetric hydroformylation of 2 could be accomplished in 66% ee using Rh/(R,S)-BINAPHOS.
