The reaction of 3-cyano-2H-cyclohepta[b]furan-2-one with enamines derived from isobutyraldehyde gave 2-amino derivatives of 3-cyano-1,1-dimethyl-1,2-dihydroazulene, which on heating with sulfuric acid underwent the elimination of amines accompanied by the migration of the methyl group to give 1,2-dimethylazulenes.
3-氰基-2H-环庚[b]呋喃-2-酮与异丁醛衍生的烯胺反应得到3-氰基-1,1-二甲基-1,2-二氢芘的2-氨基衍生物,与硫酸一起加热酸经历胺的消除,伴随着甲基的迁移,得到 1,2-二甲基芴。
