  Highly effective catalysts for the conjugate addition of silyl ketene acetals to enones (Mukaiyama-Michael reaction)

  摘要：

  Conjugate additions of O-silylated acetals to simple enones have been reported to proceed without a catalyst if acetonitrile is used as solvent. Inability to repeat this procedure led to the discovery that an as yet unknown species formed from P4O10 in acetonitrile displays high catalytic activity.

  A Convergent Synthesis of the Cardenolide Skeleton:  Intramolecular Aldol Condensation via Reduction of α-Bromoketones

  摘要：

  Synthesis of the highly biologically valuable cardenolide backbone was achieved via anionic polycyclization. Bromoketone 18, obtained from double-Michael cycloaddition between cyclohexenone 14 and gamma,delta-unsaturated beta-ketoester 16, was efficiently aldolized under reductive conditions. The highly functionalized tetracyclic compound 52 is an important synthetic intermediate that is potentially amenable to natural cardenolide total synthesis.

  Khusimone (1), one of the main odor-donating compounds of vetiver oil is subject of the following study on structure/odor relationship. The omittance of the ethano bridge of the tricyclic khusimone leads to a bicyclic system. The stereoselective approach to this degraded structure is described, and the olfactory properties are studied. The key step of the synthesis of the hydrindane nucleus is based

  bridge of the tricyclic khusimone should lead to the bicyclic partial structure (−)-2. Unexpectedly, (−)-2 could not be obtained since epimerization favored (−)-16. The stereochemical key step of the synthesis of the hydrazulene nucleus is based on a highly diastereoselective conjugate addition to a chiral oxocyclopent-1-ene-1-carboxylate.
