Abstract
A silver/DBU catalyst system was developed for the effective synthesis of cyclic carbonate and oxazolidinone from the reaction of CO 2 with propargylic alcohols and propargylic amines, respectively, in high yields under mild conditions. It was found that the [3, 3]- sigmatropic Meyer–Schuster-type rearrangement of the propargylic alcohol was mediated by CO 2 in DMF to afford the corresponding α, β-unsaturated carbonyl compounds in high ...
