ABSTRACT:
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.
