Abstract
The new preparation of 1,2-dioxobenzocyclobutene (4) via a short and efficient three-step route starting from the commercially available ninhydrin represents a superior procedure to all hitherto known syntheses of this valuable compound. The photo-extrusion of carbon monoxide from 1,3-bis(ethylendioxy)indan-3-one (2) is one of the rare examples using a decarbonylation of a five-membered cyclic ketone to prepare a highly strained and functionalized cyclobutane derivative.
