Thermolyses of three β-(benzofuran-2-yl)vinyl azides, 1a, 1b, and 1c, in which the benzofuran ring bears a hydrogen, a methyl, and a phenyl group at the 3-position, gave a benzofuropyrrole 2, a benzofuropyridine 3, and a benzofurobenzazepine 4, respectively. Photolyses of these azides gave the corresponding 2H-azirines, 7a, 7b and 7c, which on heating afforded the same heterocyclic compounds as the
三个 β-(苯并呋喃-2-基)乙烯基叠氮化物 1a、1b 和 1c(其中苯并呋喃环在 3 位带有一个氢、一个甲基和一个苯基)的热解得到苯并呋喃吡咯 2,a分别是苯并呋喃吡啶 3 和苯并呋喃苯并氮杂 4。这些叠氮化物的光解得到相应的 2H-氮杂环化合物 7a、7b 和 7c,加热后得到与乙烯基叠氮化物热解产物相同的杂环化合物。
