ACETALS OF LACTAMS AND ACID AMIDES. 73. SYNTHESIS AND SOME PROPERTIES OF DERIVATIVES OF 6-NITRO-γ-CARBOLINE

Article abstract of DOI:10.1007/BF00767002

We have developed two synthesis routes for 4-amino derivatives of 6-nitro-γ-carbolines: 1) consecutive conversion of 1,2-dimethyl-3-formyl-5-nitroindole to the 3-cyano derivative, condensation of the latter with DMF diethyl acetal, and cyclization of the
