| titleOfInvention | New heterocyclic compounds |
| abstract | Heterocyclic cpds. are formed by reacting quinone aldehydes (I) : (where R and R1 are H or lower alkyl and together opt. form part of 5- or 6-membered ring; and X, Y and Z are further substits. where X and Y together form part of an anellated (o-fussed) 5- or 6-membered carbocyclic ring) with hydrazine derivs. (II), having a free H2N-NH- gp., which do not have a reducing activity towards (I), in 1:1 mole ratio, pref. at 0-100 (10-30) degrees C, in weakly acid, neutral or pref. weakly alkaline medium, pref. using pyridine and/or alkyl pyridine catalyst, and opt. separating any isomeric linear aldehyde hydrazones formed at same time. |
