O-Heterocycles from Unsaturated Carbonyls and Dimethoxycarbene
Croisetière, Jean-Philippe,Spino, Claude
, p. 5609 - 5618 (2018)
The (4+1)-annulation of dimethoxycarbene with readily accessible α,β-unsaturated carbonyls gives cyclic orthoesters, which can then be converted in just a few steps to other O-heterocycles, including methoxyfurans, furanones, and furans.
