  Intramolecular [4+3] Cycloadditions. Studies of Relative Asymmetric Induction

  摘要：

  Treatment df both the E and Z isomers of alkoxyallylic sulfones 20a and 20b with TiCl4 results in the formation of 4 + 3 cycloadducts by intramolecular cycloaddition. The distribution of diastereomers is different from each isomer of educt. This suggests that cycloaddition occurs faster than any isomerization process of the intermediate allylic cations. Both the E and Z isomers of 20c lead to the same 4 + 3 cycloadduct with essentially complete diastereoselectivity. Inherently high simple diastereoselection and a strong conformational bias in the allylic cation intermediates for both isomers account for this selectivity. The importance of allylic cation stereochemistry in these reactions is underscored by the cyclization of 20d. The Z isomer give only 4 + 3 cycloadducts with excellent relative but poor simple diastereoselection, suggestive of a concerted reaction. The E isomer give a [3 + 2] cycloadduct, enol ether 60, as the major cycloadduct as well as 4 + 3 cycloadducts and chloride-trapping product 61. This result is indicative of a stepwise reaction. The data reflect the importance of allylic cation stereochemistry in the regiochemical and stereochemical outcomes of intramolecular 4 + 3 cycloaddition reactions.

• Kinetic resolution of primary 2-methyl-substituted alcohols via Pseudomonas cepacia lipase-catalysed enantioselective acylation
  作者：Ove Nordin、Ba-Vu Nguyen、Carin Vörde、Erik Hedenström、Hans-Erik Högberg

  DOI：10.1039/a908023f

  日期：——

  The enantioselectivities of lipases from Pseudomonas cepacia (PFL, Amano PS, etc.) towards a series of primary 2-methyl-substituted alcohols using vinyl acetate as the acyl donor in transesterifications in organic solvents were studied. In terms of enantioselectivity, the best results were found for 3-aryl-2-methylpropan-1-ols with enantiomeric ratios (E-values) over 100 in most cases, whereas other 3-substituted primary 2-methylpropan-1-ols generally displayed lower enantioselectivities: 3-cycloalkyl-2-methylpropan-1-ols (E ≈ 20) and 2-methylalkan-1-ols (E ≈ 10). Moving the aryl group closer or further away from the chiral centre resulted in low enantioselectivities: 2-arylpropan-1-ols (E < 10), 2-methyl-4-(2-thienyl)butan-1-ol (E = 12), 2-methyl-5-(2-thienyl)pentan-1-ol (E = 3.2) and 2-methyl-6-(2-thienyl)hexan-1-ol (E = 3.8).

Broad substrate scope and up to quantitative yields were achieved at low catalyst loadings with only hydrogen and water as by-products. The protocol was readily extended to the β-alkylation of alcohols with several primary alcohols. Control experiments, along with DFT calculations

  The first example of a Piancatelli rearrangement of alcohols is demonstrated utilizing dysprosium(III) triflate as a catalyst to access oxaspirocycles in a highly diastereoselective manner. The cascade reaction constructs the spirocyclic ether ring system and the tertiary stereocenter in a single operation and is experimentally easy to perform.
