Abstract

A process for preparing a compound having the essential structure of <FORM:1013906/C2/1> in which X2 is CS-NR1R2 or CO-NR1R2 in which R1 and R2 can be hydrogen or R1 and R2 when taken together with the N to which they are attached form a nitrogen heterocyclic ring such as pyrryl, piperidyl, pyrrolidyl, morpholinyl piperazyl and thiomorpholinyl; or R1 when taken separately may be, for example, hydrogen, substituted or unsubstituted lower alkyl, e.g. alkoxyalkyl, halolkyl, aralkyl containing up to a total of 10 C atoms, phenyl and di-lower alkylamino, and R2 when taken separately may be hydrogen and lower alkyl comprises treating the corresponding precursor acyl malonamate or substituted derivative thereof, e.g. having an amino or substituted amino at the alpha position having the essential structure <FORM:1013906/C2/2> in which X2 is as above and X1 is lower carbalkoxy, carboaryloxy or carbobenzyloxy with a Claisen-type condensation agent, e.g. alkali metal alkali metal hydride, alkali metal amide or metal hydride or metal alkoxide in a reaction-inert solvent at a temperature of about 60 DEG C. to about 150 DEG C. The compounds may have substituents, many being specified, and R1 and R2 may form a ring compound. The aryl malonamate starting material may be substituted on the a -position by an amino or substituted amino group -NR3R4, R3 and R4 forming a 5- or 6-membered heterocyclic ring or may be separate substituents. In an example, 3 - carboxamido - 5 - methoxy - 8 - chloro - 2,4, 10 - trioxo - 1,2,3,4,4a,9,9a,10-octahydroanthracene is prepared by reacting ethyl a -[2-(4-oxo-5-methoxy - 8 - chloro - 1,2,3,4 - tetrahydronaphthyl) - acetyl] - malonamate in dry N,N-dimethylformamide with sodium hydride. Numerous examples are given.
