A novel ring-opening based tandem domino process of an activated vinyl cyclopropane
摘要:
An activated vinyl cyclopropane reacted with substituted benzaldehydes to afford alpha-methylene gamma-butyrolactones in the presence of DABCO center dot 6H(2)O. This tandem domino process took place in aqueous media, and was presumably initiated with the ring opening of cyclopropane by the nucleophilic addition of DABCO center dot 6H(2)O.
