Synthesis and transformations of 1,4-diethynyl-2-nitrobenzene

Heating 2-nitro-1,4-bis(1,3,3-trimethylindolin-2-ylideneacetyl)benzene with POCl3 followed by treatment with an aqueous solution of NaOH gave 2-nitro-1,4-diethynylbenzene. Some transformations involving this product were considered. 2-Acetylamino-1,4-diethynylbenzene and its dimorpholinomethyl deriv...

Zusammenfassung:Heating 2-nitro-1,4-bis(1,3,3-trimethylindolin-2-ylideneacetyl)benzene with POCl3 followed by treatment with an aqueous solution of NaOH gave 2-nitro-1,4-diethynylbenzene. Some transformations involving this product were considered. 2-Acetylamino-1,4-diethynylbenzene and its dimorpholinomethyl derivative underwent heterocyclization, resulting in the terminal and methine carbon-substituted indolylacetylenes.
