Abstract

Platinum(II)-catalyzed intermolecular formal [4+3]-cycloaddition reaction of α,β-unsaturated carbene complex intermediates with siloxydienes proceeded under mild conditions to give cyclohepta[b]indole derivatives in good yield. The reaction was found to proceed via 1,2-alkyl shift of the carbene complex intermediates obtained by [4+2]-cycloaddition reaction of the unsaturated carbenes with dienes.
