  Palladium-Catalyzed Enantioselective Decarboxylative Allylic Alkylation of Cyclopentanones

  摘要：

  The first general method for the enantioselective construction of all-carbon quaternary centers on cyclopentanones by enantioselective palladium-catalyzed decarboxylative allylic alkylation is described. Employing the electronically modified (S)-(p-CF3)(3)-t-BuPHOX ligand, alpha-quaternary cyclopentanones were isolated in yields up to >99% with ee's up to 94%. Additionally, in order to facilitate large-scale application of this method, a low catalyst loading protocol was employed, using as little as 0.15 mol % Pd, furnishing the product without any loss in ee.

  Allyl β-oxo esters, allyl 1-alkenyl carbonates, and allyl α-cyano esters are converted into α,β-unsaturated ketones, aldehydes, and nitriles by palladium-catalyzed intramolecular decarboxylation-dehydrogenation. Palladium-phosphine complexes such as Pd(OAc)2-PPh3, Pd(OAc)2-dppe, or Pd2(dba)3 - CHCl3-PPh3 are effective catalysts. Yields depend on solvents and on the mole ratio of palladium to phosphine. The optimum Pd/P ratio for each substrate was determined Use of nitriles as solvents is essential for the dehydrogenation.

  烯丙基β-氧代酯、烯丙基1-烯基碳酸酯和烯丙基α-氰基酯通过钯催化的分子内脱羧脱氢反应转化为α,β-不饱和酮、醛和腈。钯-膦配合物如Pd(OAc)2-PPh3、Pd(OAc)2-dppe或Pd2(dba)3-CHCl3-PPh3是有效的催化剂。产率取决于溶剂和钯与膦的摩尔比。每个底物的最佳Pd/P比被确定。使用腈作为溶剂对脱氢是至关重要的。

  Cyclic ketones bearing α‐quaternary stereocenters underwent efficient kinetic resolution using cyclohexanone monooxygenase (CHMO) from Acinetobacter calcoaceticus. Lactones possessing tetrasubstituted stereocenters were obtained with high enantioselectivity (up to >99 % ee) and complete chemoselectivity. Preparative‐scale biotransformations were exploited in conjunction with a SmI2‐mediated cyclization
