First example of electrophile induced Baylis–Hillman reaction: a novel facile one-pot synthesis of indolizine derivativesElectronic supplementary information (ESI) available: Experimental procedures, analytical and spectral data for all the compounds 2a–i.

Treatment of pyridine-2-carboxaldehyde with activated alkenes such as alkyl vinyl ketones and cyclic enones in the presence of trimethylsilyl trifluoromethanesulfonate (TMSOTf) provides a novel facile one-pot synthesis of indolizine derivatives, thus for the first time describing an electrophile induced Baylis–Hillman reaction.
