We prepared novel 1-phenyl-1,6a-dihydro-6-oxacyclopropa[a]indene-1a-carboxylic acid derivatives starting from the Baylis-Hillman adducts via the palladium-mediated domino carbopalladation involving activation of C(sp(3))-H bond, (c) 2008 Elsevier Ltd. All rights reserved.

Modified Baylis–Hillman adducts having 2-bromoaniline moiety at the primary position underwent Pd-mediated reductive Heck type cyclization to produce dihydroindole derivatives. The same starting materials can also be used for the synthesis of indole derivatives under slightly different conditions via the concomitant δ-carbon elimination and decarboxylation process.
