  日期：2008.7

  A procedure for one-carbon homologation of unsymmetrical ketones, including one-carbon ring-expansion of 2-substituted cyclohexanones, through magnesium β-oxido carbenoid rearrangement as the key reaction is described. Addition of the α-sulfinyl carbanion of 1-chloroethyl p-tolyl sulfoxide to an unsymmetrical ketone gave two diastereomers as adducts in good yields. The adducts were treated with a base

  描述了一种通过不对称酮的一碳同系化（包括2-取代的环己酮的一碳环扩展）通过镁β-氧化类胡萝卜素重排作为关键反应的方法。1-氯乙基p的α-亚磺酰基碳负离子的加成甲苯磺酸亚砜制得不对称酮后，以高收率得到了两种非对映异构体作为加合物。将加合物用碱处理以得到醇盐，将其用格氏试剂处理以得到β-氧化类胡萝卜素镁。然后进行β-氧化类胡萝卜素重排，以提供在α-位具有甲基的一碳同系酮。在重排中观察到显着的特异性或选择性。发现该反应的烯醇镁中间体能够被数种亲电试剂捕获，从而得到一碳同系的α，α-二取代的酮。还讨论了特异性和选择性的起源。

  A process of the present invention produces an organic compound by allowing a compound containing an electron attractive group of following Formula (1): 1 wherein Y is an electron attractive group; and R b and R c are each a hydrogen atom or an organic group, where Y, R b and R c may respectively be combined with each other to form a ring with an adjacent carbon atom, to react with a compound containing an unsaturated carbon-carbon bond of following Formula (2) or 2 wherein R d , R e , R f , R g , R i and R j are each a hydrogen atom or an organic group, where R d , R e , R f and R g may respectively be combined to form a ring with one or two adjacent carbon atoms, and R i and R j may be combined to form a ring with adjacent two carbon atoms, in the presence of oxygen and a catalytic compound of a Group 5, 6, 7, 8 or 9 element of the Periodic Table of Elements to yield a compound of following Formula (3) or (8): 3 wherein Z is a hydrogen atom or a hydroxyl group; and Y, R b , R c , R d , R e , R f , R g , R i and R j have the same meanings as defined above. This process can efficiently produce a compound having an alkyl group or alkenyl group bonded at the alpha position of an electron attractive group, or a derivative thereof, by catalytic radical addition reaction.

  本发明的一种过程通过允许含有下式（1）中的电子亲合基团的化合物与含有下式（2）的不饱和碳-碳键的化合物在氧气和周期表元素的5、6、7、8或9族的催化化合物存在下反应，产生下式（3）或（8）的化合物： 其中Y是一个电子亲合基团；Rb和Rc分别是氢原子或有机基团，其中Y、Rb和Rc可以分别结合在一起形成与相邻碳原子的环；Rd、Re、Rf、Rg、Ri和Rj分别是氢原子或有机基团，其中Rd、Re、Rf和Rg可以分别结合在一起形成与一个或两个相邻碳原子的环，而Ri和Rj可以结合在一起形成与相邻两个碳原子的环。这个过程可以通过催化自由基加成反应高效地产生在电子亲合基团的α位结合有烷基或烯基基团的化合物，或其衍生物。

  Radical addition of ketones to alkenes catalyzed by Mn(OAc)2 combined with Co(OAc)2 using dioxygen as oxidant was developed; for instance, the reaction of cyclohexanone with oct-1-ene in the presence of very small amounts of Mn(OAc)2 and Co(OAc)2 under air (1 atm) gave 2-octylcyclohexanone in good selectivity; from styrene, a six-membered cyclic peroxide was isolated in good yield.

  开发了以分子氧为氧化剂Mn(OAc)2与Co(OAc)2催化烯烃自由基加成反应；例如，在空气（1 atm）下，在极少量的 Mn(OAc)2 和 Co(OAc)2 存在下，环己酮与 oct-1-ene 反应得到具有良好选择性的 2-辛基环己酮；从苯乙烯中，以良好的收率分离出六元环状过氧化物。
