Homochiral Ketals in Organic Synthesis. Enantioselective Synthesis of (R)-Muscone
Nelson, Keith A.,Mash, Eugene A.
, p. 2721 - 2724 (2007/10/02)
An efficient, enantioselective preparation of (R)-muscone employing a diastereoselective Simmons-Smith cyclopropanation is described.Cyclopropanation is directed via chelation control by a homochiral ketal protecting group derived from unnatural tartaric acid.The overall yield of (R)-muscone (>95percent R) from commercially available cyclopentadecanone is 60percent over seven steps.
