  摘要：

  已经开发了一种普遍，有效和经济的钯催化脱氢形成烯酮或烯醛的方法。该方法具有极其广泛的底物范围，包括各种线性或环状的饱和酮和醛。该方案不含配体，并且分子氧被用作反应中唯一的清洁氧化剂。由于温和的反应条件，良好的官能团相容性以及烯酮和烯醛的多用途，该方法可用于天然产物，药物和精细化学品的后期合成。

  An organocatalytic asymmetric Nazarov cyclization of diketoesters that proceeds by means of a dual activation mechanism has been developed. Screening of a number of catalysts led to a new thiourea that incorporates a primary amino group. The method gives rise to cyclic products with two adjacent quaternary asymmetric carbon atoms, one of which is an all-carbon stereocenter, with complete or nearly

  expensive catalyst from the product mixture. In this view we prepared a polyester-based Pd catalytic system that offers the advantages of both homogenous and heterogeneous catalyses: efficacy, selectivity and recyclability. Here its application in the hydrogenation of selected α,β-unsaturated carbonyl compounds is described.

  均相催化是进行氢化过程的有效工具，但主要缺点是从产物混合物中分离出了昂贵的催化剂。根据这种观点，我们制备了一种基于聚酯的钯催化体系，该体系具有均相和异相催化的优点：功效，选择性和可回收性。在此描述了其在选择的α，β-不饱和羰基化合物的氢化中的应用。

  The present invention provides a catalyst used for manufacturing an optically active carbonyl compound by selective asymmetric hydrogenation of an α,β-unsaturated carbonyl compound, which is insoluble in a reaction mixture, and a method for manufacturing the corresponding optically active carbonyl compound. Particularly, the invention provides a catalyst for obtaining an optically active citronellal useful as a flavor or fragrance, by selective asymmetric hydrogenation of citral, geranial or neral. The invention relates to a catalyst for asymmetric hydrogenation of an α,β-unsaturated carbonyl compound, which comprises: a powder of at least one metal selected from metals belonging to Group 8 to Group 10 of the Periodic Table, or a metal-supported substance in which the at least one metal is supported on a support; an optically active peptide compound; and an acid, and also relates to a method for manufacturing an optically active carbonyl compound using the same.

  Joining the circle: The first Pd0 catalyzed Nazarov‐type cyclization of diketoesters (see scheme) proceeds in 70 % to 95 % yield under strictly neutral pH conditions. Aryl substitution of the diketoesters is not required, so the reaction shows great versatility and can also proceed with aliphatic substrates.
