A Formal Synthesis of (+)-Juvabione

A formal synthesis of (+)-juvabione is presented based on the diastereoselective addition of the enolate of N-acyloxazolidinone 3 with η6-(C6H5OC6H5)Mn(CO)3BF4.Key Words: Juvabione, asymmetric, diastereoselective, organomanganese arene complex,

STEREOSELECTIVE SYNTHESES OF STEROID SIDE CHAINS. EFFICIENT SYNTHESES OF (2RS,3RS)-2-METHYL-3-CYCLOPENTANONE AND (2RS)-2-PROPANOIC ACID

The title compounds, key intermediates in the syntheses of (+/-)-vitamin D3 and (+/-)-erythro-juvabione, have been prepared in short steps using stereoselective cleavage reactions of the cyclopropane derivatives.
