Gold-catalyzed reactions between alkenyldiazo carbonyl species and acetals.

Abstract

In the presence of catalyst IPrAuSbF6 catalyst (IPr = 1,3-bis(diisopropylphenyl)imidazol-2-ylidene), alkenyldiazo carbonyl species react with organic acetals to give E-configured alkyl 3,5-dimethoxy-5-pent-2-enoates stereoselectively. This reaction sequence comprises an initial Prins-type reaction, followed by gold carbene formation.
