摘要
The reaction of the isothiourea derivative 2 with mcthylaminc or pyrrolidine resulted in guanidines 3a-3b. Using hydrazine under the same conditions the tetrazole derivative 4 was obtained. On reacting 2 with piperidine, morpholine, methylhydrazine, phenylhydrazine, hydroxylamine or sodium hydroxide, cyclization took place leading to the novel 4-cyanimino-1,2,3,4,6,7,12, 12b-octahydro-3,12b-ethanopyrimido[1',6':1,2]pyrido[3,4-b]indole (5). Some structural aspects of 5 and other model compounds were analysed mainly by C-13 nmr spectroscopy.
