摘要 R-2-氨基-3-甲基-1,1-二苯基-1-丁醇是一种合成手性催化剂的重要中间体。从原料R-缬氨酸经甲酯化,苄氧羰基保护制得R-2-苄羰基氨基-3-甲基-丁酸甲酯,然后与苯基溴化镁反应制得(R)-2-苄氧羰基氨基-3-甲基-1,1-二苯基-1-丁醇。接着在5%Pd/C催化加氢下脱除苄氧羰基得到目标化合物,总收率58%。此制备方法涉及的中间体及目标化合物易于纯化,总收率高且重现性好。 R-2-amino-3-methyl-1,1-diphenyl-1-butanol is an important catalyst for synthesis of chiral intermediates.R-valine generated(R)-2-benzyloxycarbonyl-amino-3-methyl-1,1-diphenyl-1-butanol through esterification,CBZprotection.Then through 5% Pd/C catalytic hydrogenation yelid R-2-amino-3-methyl-1,1-diphenyl-1-butanol in an overall yield of 58%.
