Abstract

Rhodium(II) acetate catalyzed decomposition of vinyldiazomethanes in the presence of N-alkoxycarbonylpyrroles provides a direct entry to the skeleton of tropane alkaloids. Similar reactions with N-alkylpyrroles result in the formation of alkylation products.

Rhodium(II) acetate catalyzed decomposition of vinyldiazomethanes in the presence of N-alkoxycarbonylpyrroles provides a direct entry to the skeleton of tropane alkaloids.

    Intermolecular reactions of carbenoids with heteroatomic molecules, which allow the use of more simple and available starting materials are also well known and extensively developed. The reactions of metallocarbenoids with monoheterocyclic substrates can result in the formation of ortho-fused1 or bridged2 heterocyclic systems, the products of formal C–H insertion1d,2a,3 and recyclization, which can occur with retention of ring size,4 ring contraction5 or with ring enlargement. Carbenoid-mediated ring enlargement can occur as one-carbon ring expansion by formal insertion of a carbene moiety into the carbon–heteroatom bond6 or a three-atom ring expansion.
