Condensation of diethyl formylamino- or diethyl acetylaminomalonate with 4-, 5- or 6-nitrogramine 1 afforded the diethyl formylamino- or the diethyl acetylamino[(nitroindol)-3-ylmethyl]malonates 2; reduction of the nitro group followed by N-formylation or acetylation of the resulting amino compounds 3, led to the 4-, 5-and 6-acylamino derivatives 4.
