资源简介：
The reaction of 3-cyanophthalides with allene carboxylates in the presence of tBuOLi results in a tandem annulation furnishing naphtho[b]furanones in good yields with no loss of carbon. The carbon economy is explained by a tandem process, in which the initially expelled cyanide induces the second annulation.
