A method for the chemoselective reduction of Ugi-type lactam amides at the lactam carbonyl functionality with borane complexes has been developed. The novel reduction products can be further manipulated synthetically to yield various novel N- and C-terminally active unnatural amino acid building blocks.
已经开发了一种用硼烷配合物在内酰胺羰基官能团上化学选择性还原Ugi型内酰胺酰胺的方法。新型还原产物可以进一步合成处理以产生各种新型的N-和C-末端活性的非天然氨基酸构件。
