Furobenzoxazin-3-one, a new tricyclic nucleus, was synthesised in two different and straightforward routes: the first route consisted of condensing a furan ring onto a preconstituted 1,4-benzoxazinone nucleus, and the other in condensing a 1,4-oxazine ring onto the appropriate benzofuran system obtained from coumarin by ring contraction.

Furobenzoxazin-3-one,一个新的三环核,是通过两种不同而直接的途径合成的:第一种途径是将呋喃环缩合到预制的1,4-苯并恶嗪酮核上,另一种途径是缩合1,4-恶嗪。环缩合到从香豆素获得的合适的苯并呋喃体系上,该体系通过环收缩而得到。(©Wiley-VCH Verlag GmbH,69451 Weinheim,Germany,2002)
