de Mayo reaction
Photochemical process leading to the formation of cyclobutanols by @C01496@ of an alkene to a 1,3-dicarbonyl-enol. The enol originates in most cases from the @T06253@ of a 1,3-dicarbonyl compound. The products of the de Mayo reaction are susceptible to undergo a @R05370@-aldol ring opening resulting in the formation of 1,5-dicarbonyl compounds.
