Highly Diastereoselective Preparation of anti-1,2-Diols by Catalytic Addition of Alkynylsilanes to α-Silyloxyaldehydes
摘要:
The catalytic, diastereoselective coupling of alpha-silyloxy aldehydes and alkynylsilanes catalyzed by a nickel(0) N-heterocyclic carbene complex provides an effective entry to anti-1,2-diols. The scope of couplings and extent of diastereoselection are excellent across a range of substrates.
