DUAL REACTIVITY OF 1,2-DISUBSTITUTED DIHYDRO-N-HETEROAROMATIC SYSTEMS. 9. ALKALINE HYDROLYSIS AND AROMATIZATION OF N-ACYL PARTIALLY HYDROGENATED DERIVATIVES OF PYRAZINE AND QUINOXALINE

Article abstract of DOI:10.1007/BF00515230

The aromatization with splitting of the N-acyl groups of 2,3-disubstituted N-acyl- and N,N'-diacyl-1,2-dihydro-, and 1,2,3,4-tetrahydropyrazines and quinoxalines under the effect of alcohol alkali was studied.A new reaction of recyclization of 1,4-diacyl-1,2,3,4-tetrahydroquinoxaline was discovered.
