- W2949340764 abstract "Two possible routes have been investigated for the synthesis of 1-heterocycloheptatrienes starting from annulated cyclobutene derivatives. The first approach comprised a [2 + 2 + 2] cycloreversion of tetracyclic compounds prepared from 2,3-bis(methoxycarbonyl)-7-oxa- or −7-azabicyclo-[2.2.1]hepta-2,5-diene by a [2 + 2] cycloaddition with ynamines followed by a cycloaddition reaction with a 1,3-dipolar reagent However, upon flash-vacuum pyrolysis of these compounds, a retro-1,3-dipolar addition rather than a [2 + 2 + 2] cycloreversion occurred, yielding 2,4,6-trimethylbenzonitrile oxide. The second approach comprised the synthesis and isomerization of [2 + 2] cycloadducts of ynamines with electron-deficient heteroaromatics. Both 3-nitrobenzo[b]thiophene and 4-nitro-isothiazole yielded [2 + 2] cycloadducts and as the by-product nitrones. Attempts to convert the [2 + 2] cycloadducts into benzo[b]thiepins or 1,2-thiazepines were unsuccessful." @default.
