Abstract

Abstract Efficient procedures were developed for the two-step synthesis of 1, 2, 2, 3- tetramethyl-2, 3-dihydroperimidines and for the one-step synthesis of 1, 3-dimethyl-2, 3- dihydroperimidines starting from 1, 8-diaminonaphthalenes. New possibilities of the use of 2, 3-dihydroperimidinium salts in the synthesis of 1, 8-bis (dialkylamino) naphthalenes (“proton sponges”) containing the N-isopropyl group along with the N-methyl groups were ...
