  Rhodium-mediated cyclopentane construction can compete with .beta.-hydride elimination: synthesis of (.+-.)-tochuinyl acetate

  摘要：

  Rhodium(II) carboxylate catalyzed C-H insertion to form a cyclopentane is shown to compete effectively with beta-hydride elimination, except when the beta-hydrogen is ternary. Cyclization of diazo ester 27 gives 28, which is converted in three steps to (+/-)-tochuinyl acetate 25. Both the cyclization to form 28 and the alkylation of 28 proceed with remarkable diastereoselectivity.

  Reaction in methylene chloride of bis(collidine)bromine(I) hexafluorophosphate with alpha,beta-unsaturated acids and alpha,beta-unsaturated N-sulfonamides was found to lead diastereospecifically to the corresponding 2-oxetanones and 2-azetidinones in moderate yields (23-60%), by an almost unknown 4-endo cyclization. This process allow the synthesis of these interesting classes of products in one step

  aldehydes undergo an efficient E-stereoselective Horner-Wadsworth-Emmons olefination by generation of phosphonate carbanion with lithium hydroxide. The reaction proceeds satisfactorily with linear, cyclic, polifunctional ketones in the presence of activated zeolites and and by the slow addition of the base.
