Highly Enantioselective Direct Reductive Coupling of Conjugated Alkynes and a-Ketoesters via Rhodium-Catalyzed Asymmetric Hydrogenation

Chemical with cas number 595-91-5 also plays role. Highly Enantioselective Direct Reductive Coupling of Conjugated Alkynes and a-Ketoesters via Rhodium-Catalyzed Asymmetric Hydrogenation. Kong, Jong-Rock; Ngai, Ming-Yu; Krische, Michael J. (Department of Chemistry and Biochemistry, University of Texas at Austin, Austin, TX 78712, USA). Journal of the American Chemical Society, 128(3), 718-719 (English) 2006 American Chemical Society. CODEN: JACSAT. ISSN: 0002-7863. DOCUMENT TYPE: Journal CA Section: 23 (Aliphatic Compounds) Catalytic hydrogenation of 1,3-enynes in the presence of Et pyruvate and related activated ketones using chirally modified cationic rhodium catalysts results in reductive coupling to afford dienylated a-hydroxy esters with exceptional levels of regio- and enantiocontrol. These studies represent the first highly enantioselective direct catalytic reductive couplings of alkynes to ketones. As illustrated by the reactions of CH2:CHCH:CPhC(OH)MeCO2Et, the diene contg. side chain of the coupling products is subject to diverse chemo- and regioselective manipulation. Reductive coupling of CH2:CHCYCCH2NHBoc and Et pyruvate using elemental deuterium provides the monodeuterated product, consistent with a catalytic mechanism involving alkyne-carbonyl oxidative coupling followed by hydrogenolytic cleavage of the resulting oxametallacycle, as corroborated by ESI-MS anal. . 595-91-5 which is the cas registry number of one of substances is just one of reagents here..
