Abstract

Abstract Starting from 1 the azomethine 2 is obtained. The intermediates 4 a and 4 b of this reaction sequence cause the high yields. Cyclization of the N-alkylderivatives 4 d and 8 b leads also to an azomethine, which is obtained as its salt 11. Cyclization of the N- acetylderivative 13 yields however the anamine 14. The structures of the new products are established by chemical and spectroscopic methods.
