Copper-catalyzed cascade aminoalkynylation–oxidation of propargylic alcohols has been realized, sterospecifically providing an array of (Z)-2-amino conjugated enynals/enynones in good yields under mild conditions. This transformation involves a rare 1,3-alkynyl migration of propargylic alcohols and simultaneously forms C–C, C–N, and C═O bonds. Furthermore, (Z)-2-amino conjugated enynals were applied
A silver/DBU catalyst system was developed for the effective synthesis of cyclic carbonate and oxazolidinone from the reaction of CO2 with propargylicalcohols and propargylic amines, respectively,...
a cationic rhodium(I)/Solphos complex-catalyzed asymmetric one-pot transesterification and [2 + 2 + 2] cycloaddition of 1,6-diyne esters with tertiary propargylic alcohols leading to enantioenriched tricyclic 3,3-disubstituted phthalides. The present method represents a versatile new route to the synthesis of enantioenriched tricyclic 3,3-disubstituted phthalides in view of the easy access to both coupling
The combined catalyst system of silver acetate with a chiral Schiff base ligand achieved asymmetric carbondioxideincorporation into bispropargylic alcohols with desymmetrization to afford the corresponding cyclic carbonates with good-to-excellent enantiomeric excesses.
