The present invention relates to substituted bicyclo[3.3.1]nonanes and bicyclo[3.3.1]nonenes of formula (I) wherein R, and R1 to R5 have the same meaning as described in the specification.
The nucleophilic γ-phenylation and γ-alkylation of α,β-unsaturated amides have been developed. This umpolung reaction allows the regioselective introduction of phenyl and alkyl groups to a vinylketene N,O-acetal, which is generated in situ from an α,β-unsaturated N-alkoxyamide, followed by N-O bond cleavage in a two-step, one-pot process.
