    名称:
    Asymmetric Hydrogenation of Substituted 2-Pyrones
    摘要:
    Various substituted 2-pyrones have been hydrogenated with high enantioselectivity (up to 97% ee) to the corresponding 5,6-dihydropyrones using cationic ruthenium catalysts containing the (6,6'-dimethoxybiphenyl-2,2'diyl)bis[3,5-di(tert-butyl)phenylphosphine] ligand. When substituents at position 3 are absent, 5,6-dihydropyrones are further hydrogenated to the fully saturated delta-lactones. In the case of 4,6-dimethyl-2H-pyran-2-one, the diastereoselectivity of the second hydrogenation step was determined by the chirality of the applied catalyst, while for the 4,5,6-trimethyl-2H-pyran-2-one a double asymmetric induction effect was observed. Other cyclic substrates with endo- or exocyclic double bonds were hydrogenated, although with substantially lower enantioselectivity with respect to the 2-pyrones.

    protein (BMP) and activation of p38 MAPK signaling pathways. Compounds 14 and 21 also inhibited RANKL-induced osteoclast differentiation of RAW264 cells. These results indicated that novel 5,6-dehydrokawain analogs not only increase osteogenic activity but also inhibit osteoclast differentiation, and could be potential lead compounds for the development of anti-osteoporosis agents.

    Herein, we disclose our efforts directed toward the synthesis of the kavalactone-based natural product penstyrylpyrone and other related 4-OMe-2-pyrones possessing diverse substituents at the 3-, 5-, and 7-positions. Further, a facile approach to access 6-styrylpyrones via the KHMDS-mediated regioselective aldol condensation of 2-pyrones is described with moderate substrate scope and good to high yields
    在此,我们公开了我们致力于合成基于 kavalactone 的天然产物 penstyrypyrone 和其他相关的 4-OMe-2-pyrones,这些 4-OMe-2-pyrones 在 3-、5-和 7-位具有不同的取代基。此外,描述了一种通过KHMDS 介导的 2-吡喃酮的区域选择性羟醛缩合获得 6-苯乙烯基吡喃酮的简便方法,具有中等底物范围和良好到高产率(58-80%)。这种方法的效用通过去甲氧基仰光素、asnipyrone A 和 asnipyrone B 的立体选择性构建得到了例证。

    3‐Oxo‐5‐alkynoic acid esters, on treatment with a carbophilic catalyst, undergo 6‐endodig cyclization reactions to furnish either 2‐pyrones or 4‐pyrones in high yields. The regiochemical course can be dialed in by the proper choice of the alcohol part of the ester and the π‐acid. This transformation is compatible with a variety of acid‐sensitive groups as witnessed by a number of exigent applications

Incorporation of [17,17,18,18,18-2H5]prosolanapyrone I (6b) afforded solanapyrones A (1) labelled at C-17 and C-18 with the expected integration in its 2H NMR spectrum. Subsequently, [2,3,17,18,18,18-2H6]prosolanapyrone II (7a) was incorporated into solanapyrone A labelled, as expected, at C-2, C-3, C-17 and C-18. These results
