Efficient Approach

The first asymmetric tandem conjugate addition–protonation to methylene 1,3-oxazolidine-2,4-diones has been developed, thus providing a direct and efficient approach to assemble chiral secondary C–O bonds for quaternary carbon stereocenters and thiols at the nonadjacent β-position.
