"Gas-solid-phase" method for the preparation of some cyclic dipeptides, 2,5-dioxopiperazines (diketopiperazines), is described. The method implies cyclodimerization of vaporous aliphatic α-amino acids in the presence of silica at reduced pressure and yields optically active 2,5-dioxopiperazines.
描述了一种用于制备某些环状二肽和2,5-二氧庚哌嗪(双酮哌嗪)的“气固相”方法。该方法是在减少压力的情况下,在二氧化硅存在下,对气相脂肪族α-氨基酸进行环状二聚化,产生光学活性的2,5-二氧庚哌嗪。
