The rhodium(I1) acetate catalyzed decomposition of diethyl 4-diazopent-2enedioate in the presence of furans results in the formation of products derived from a [3 + 41 cycloaddition. The [3 + 4] cycloaddition of ally1 cations with dienesls2 has become a very useful method for the synthesis of seven-

In the presence of the N-heterocyclic carbene gold catalyst (NHC-AuIPr, 7), propargyl esters 1a-f and 13 undergo a [4C + 3C] cycloaddition reaction with cyclopentadiene and furan under mild conditions. The evidence suggests the formation of the seven-membered ring occurs by a direct cycloaddition pr
