An unusual transition-metal-mediated [2 + 2 + 2] cyclization of functionalized alkenes

Abstract

The metal–η3-2-methoxycarbonylpentadienyl complexes (C5R5)M(CO)2(syn-Ti3-2-COOMe-C6H5)(R[double bond, length half m-dash]H, M[double bond, length half m-dash]W; R[double bond, length half m-dash]H, Me, M[double bond, length half m-dash] Mo) undergo a novel acid-catalysed cotrimerization with a- and (3-unsaturated ketones to afford two products with diastereoisomeric six-membered rings which have been structurally characterized by X-ray diffraction.
