Abstract

The reaction of acyl perchlorates with 1-phenacylskatole affords the previously unknown 1-R-10-methyl-3-phenylindolo[2,1-c]-1,4-oxazinium salts, which undergo recyclization by the action of ammonia to the corresponding indolo[2,1-a]pyrazines. It is found that the salts (R = CH3, C2H5) also form dimers of their anhydro bases. The perchlorate (R = Ph) is converted to indolo[2,1-d]-1,2,5-triazepine by the action of hydrazine.
