PHOTOCHEMICAL CYCLOBUTANONE EXPANSIONS

As a model for a new approach to bond formation at anomeric carbons, the addition of various heteroatom derivatives to oxacarbenes generated by the photochemical ring expansion of cyclobutanones has been examined.Practical procedures have been developed for the insertion of such carbenes into heteroatom-H bonds from alcohols, thiols, and amines using minimal excess trapping reagent.
