rhodium-catalyzed remote C(sp3 )-H borylation of silylenolethers (SEEs, E/Z mixtures) by alkene isomerization and hydroboration is reported. The reaction exhibits mild reaction conditions and excellent functional-group tolerance. This method is compatible with an array of SEEs, including linear and branched SEEs derivedfrom aldehydes and ketones, and provides direct access to a broad range of structurally
Mevalonolactone derivatives were prepared via stereo-and regioselective bromolactonization of γ, δ-unsaturated acids and their structure-activity relationship in connection with their inhibitory activity in vitro against 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase, a rate-limiting enzyme in cholesterol biosynthesis, was investigated.
