A new method of synthesis of racemic β-amino acids 6 by reduction of masked N-substituted and N-unsubstituted β-enamino acid derivatives 4via C-protected β-amino acids 5 is described. The process occurs with high yields, total chemoselectivity and moderate diastereoselectivity. Readily available starting materials, inexpensive reagents and mild conditions are used to furnish derivatives 5 and 6.
描述了一种新的合成外消旋β-氨基酸6的方法,该方法通过经由C-保护的β-氨基酸5还原被掩蔽的N-取代的和N-未取代的β-烯酸衍生物4。该过程以高收率,总化学选择性和中等非对映选择性发生。容易获得的起始原料,廉价的试剂和温和的条件用于提供衍生物5和6。
