This invention relates to novel derivatives of thiopyranopyrrole of general formula (I): ##STR1## in which R is hydrogen, allyl, or a radical having the structure: --CR.sub.a R.sub.b R.sub.c where R.sub.a and R.sub.b are hydrogen atoms or phenyl radicals optionally substituted (by halogen, alkyl, alkyloxy or nitro), and R.sub.c is defined as R.sub.a and R.sub.b or stands for an alkyl or alkyloxyalkyl radical, at least one of R.sub.a, R.sub.b and R.sub.c being a substituted or unsubstituted phenyl radical, and n is 0 to 2, in their stereoisomer forms, and mixtures thereof, and possibly the salts if they exist, and preparation thereof. The novel derivatives of the invention are particularly interesting as synthesis intermediates.
