  A process for preparing functional group-containing olefinic compounds comprising the steps of (a) reacting (1) at least one functional group-containing nucleophile with (2) at least one carbonyl-containing compound that comprises at least one group that is a leaving group, or that is capable of subsequent conversion to a leaving group, and that optionally comprises one or more isolated carbon to carbon double or triple bonds, to form the corresponding functional group-containing carbonyl-containing compound, said carbonyl-containing compound being selected from the group consisting of ketones and aldehydes; and (b) reacting said functional group-containing carbonyl-containing compound with at least one alkylidene phosphorane comprising an alkylidene moiety and three other moieties bonded to its phosphorus atom, said alkylidene moiety optionally comprising one or more carbon to carbon double or triple bonds, to form a functional group-containing olefinic compound.

  一种制备含官能团烯烃化合物的工艺，包括以下步骤 (a) 使(1)至少一种含官能团的亲核体与(2)至少一种含羰基的化合物反应，该化合物包含至少一个离去基团或可随后转化为离去基团的基团，并可选择包含一个或多个孤立的碳对碳双键或三键，以形成相应的含官能团的含羰基的化合物，所述含羰基的化合物选自由酮和醛组成的组；(b) 使所述含官能团的羰基化合物与至少一种亚烷基磷烷反应，所述亚烷基磷烷包括一个亚烷基分子和与磷原子成键的另外三个分子，所述亚烷基分子可选择包括一个或多个碳对碳双键或三键，以形成含官能团的烯烃化合物。

• Prosthetic Valve with Sealing Members and Methods of Use Thereof

  Embodiments of the present invention provide prosthetic valves having sealing members on the external surface thereof. The prosthetic heart valves of the present invention are preferably delivered by catheter directly through the apex of the heart or by other close range transcatheter delivery methods. Because these methods of implantation require a shorter length of catheter, a prosthetic valve can be more accurately oriented in the desired implantation location. Fluoroscopy can be used to further assist in orientation of the valve. The sealing members of the present invention can be positioned on the prosthetic valve such that, when the prosthetic valve is implanted in a native annulus, each provided sealing member is located adjacent to a commissural point of the native valve leaflets. Because the sealing members are precisely oriented on the prosthetic valve, a physician can ensure that the sealing members are aligned with the commissural points of the native valve leaflets. In embodiments of the present invention, the prosthetic valve can have a waisted middle section, and the sealing members can be located in the waisted middle section such that the crimped diameter of the prosthetic valve is not negatively impacted by the sealing members.

  DOI：10.1021/jo300519g

  日期：2012.5.4

  The first total synthesis of the polyketide apiosporic acid is presented. Key steps are a Julia–Kocienski olefination, a Suzuki–Miyaura cross-coupling, and an intramolecular Diels–Alder reaction. The absolute configuration of the natural product was determined.
