1-Pyrrole- and 1-pyrrolidine-carboxylic acid derivatives corresponding to the general formula: ##STR1## in which R represents an alkyl radical having from 1 to 4 carbon atoms, preferably ethyl, and Am represents a group: ##STR2## wherein R.sub.1 represents a 3-oxo-alkyl radical ##STR3## or a 3-oxo-alkenyl radical ##STR4## and R.sub.2 represents hydrogen or R.sub.1 and R.sub.2, when they are identical, each represent hydrogen, ##STR5## R.sub.3 representing an alkyl radical having from 1 to 5 carbon atoms with the proviso that when R.sub.1 and R.sub.2 are simultaneously hydrogen, Am represents the group A. The novel derivatives are useful as intermediates for synthetizing azaprostaglandines.
1-吡咯和1-吡咪啉羧酸衍生物对应于一般公式:##STR1##
其中R代表具有1至4个碳原子的烷基基团,优选乙基,Am代表一个基团:##STR2##
其中R.sub.1代表3-氧代烷基基团##STR3##或3-氧代烯基基团##STR4##,R.sub.2代表氢或R.sub.1和R.sub.2,当它们相同时,每个代表氢,##STR5## R.sub.3代表具有1至5个碳原子的烷基基团,但当R.sub.1和R.sub.2同时为氢时,Am代表基团A。这些新颖的衍生物可用作合成氮代前列腺素的中间体。
