Silylative Carbocyclization of Allenyl-carbonyl Units with Et3SiH Catalyzed by Rhodium: Cis-Stereoselective Synthesis of Homoallylic Cycloalkanols
摘要:
GraphicsA new procedure for the synthesis of cis-2-triethylsilylvinyl-cyclopentanois and -cyclohexanols from allenyl-aldehydes and -ketones with Et-3-SiH through rhodium-catalyzed silylative carbocyclization is described. The use of Rh(acac)(CO)(2) (1 mol %) to promote the reaction results in a mild and convenient protocol for the three-component assembly.
