The rubber tree (Hevea brasiliensis) is exploited mainly for latex in view of its economic importance. However, one of its auxiliary products, the rubber seed, does not find any major applications, and hence, even the natural production of seeds itse

Thermal cyclization reactions of N-alkyl-2-benzylaniline 1a-d and N-alkyl-N′-phenyl-o-phenylenediamine 2a-b were carried out expecting to get seven-membered heterocyclic compounds. However, the results show that aside from the formation of the norm
