Intramolecular Prins Reactions of Vinylcyclopropanes with Aldehydes and Ketones: A New Synthesis of Semicyclic Conjugated Dienes

Abstract

Carbonyl compounds bearing pendant vinylcyclopropanes react with sulfonic acids to produce semicyclic conjugated dienes. These functionalized dienes can be readily elaborated into complex polycyclic compounds.

vinylcyclopropane - cyclizations - ring opening - eliminations - conjugated diene

It is commonly accepted that acid-catalyzed dehydrations of tertiary alcohols occur via an E1 mechanism:

However, the reluctance of 30 to undergo the acid-catalyzed dehydration suggests that the presumed elimination 31 → 29 is unlikely to proceed through a free carbocationic intermediate. We suppose that the elimination step, which involves an intermediate oxonium species, lies on the carbocationic side of the E2 mechanistic spectrum with the tosylate anion serving as a weak base. It is well known that the weak base-mediated E2 processes display strong preference for anti-elimination:
