A process for producing a compound of formula ID:
where R1 is haloalkyl, R2 and R4 are alkyl, R5 is generally hydrogen or alkyl and R6 is an acid labile group, by reacting a compound containing a substituent -C(R3X)NCH2C(O)OR4, where R3 is hydrogen or alkyl and X is O or S, with an alkali metal amide base and a compound R6NHCH(R5)C(O)R7 where R7 is an activated acid moiety.
一种生产式 ID 化合物的工艺:
其中 R1 为卤代烷基,R2 和 R4 为烷基,R5 一般为氢或烷基,R6 为易受酸作用的基团,其方法是将含有取代基-C(R3X)NCH2C(O)OR4(其中 R3 为氢或烷基,X 为 O 或 S)的化合物与碱
金属酰胺基和化合物 R6NHCH(R5)C(O)R7(其中 R7 为活化的酸分子)反应。
