A process for the preparation of carboxyalkyldipeptide compounds of the Formula
is described wherein
R6 is hydroxy, loweralkoxy, or amino;
R, R2 and R7 are hydrogen or loweralkyl;
R3 is, e.g., hydrogen, or
loweralkyl,
R' is, e.g., hydrogen, or
alkyl of from 1 to 20 carbon atoms,
R4 is hydrogen or
loweralkyl,
R5 is, e.g., hydrogen, or
loweralkyl, and,
R4 and R5 may be connected together to form an alyklene bridge of from 2 to 4 carbon atoms.
The process comprises reacting a compound of the Formula
with a dipeptide (or protected dipeptide) of the Formula
and an alkali metal cyanide or a trimethylsilycyanide, to form an amino nitrile compound of the Formula
followed by hydrolysis.
These compounds are useful as converting enzyme inhibitors and as antihypertensive agents.
描述了一种制备Formula的羧基烷基二肽化合物的过程,其中R6为羟基、低烷氧基或氨基;R、R2和R7为氢或低烷基;R3为氢、低烷基等;R'为氢、1-20碳原子的烷基等;R4为氢或低烷基;R5为氢、低烷基等,R4和R5可以连接在一起形成2-4个碳原子的烷基桥。该过程包括将Formula的化合物与Formula的二肽(或保护的二肽)和碱金属氰化物或三甲基硅氰化物反应,形成Formula的氨基腈化合物,然后进行水解。这些化合物可用作转化酶抑制剂和降压剂。
