  Enantioselective Diels−Alder Cycloadditions with (SS)-2-(p-Tolylsulfinyl)-1,4-naphthoquinone:  Efficient Kinetic Resolution of Chiral Racemic Vinylcyclohexenes

  摘要：

  Chiral racemic vinylcyclohexenes 1a-m, bearing allylic and nonallylic oxygenated substituents on the cyclohexene ring, were submitted to Diels-Alder reactions with enantiomerically pure (SS)(2-p-tolylsulfinyl)-1,4-naphthoquinone. The tandem cycloaddition/pyrolytic sulfoxide elimination led to the formation of enantiomerically enriched angularly tetracyclic quinones (+)-8a and (+)-12, arising from the kinetic resolution of the racemic diene. Dienes la-c, bearing an alkoxy substituent at the allylic position C-3, and 1d-g, with C-3 alkoxy and C-5 methyl groups, gave exclusively quinones (+)-8a-g, resulting from the anti approach to the dienophile. A similar anti selectivity occurred in cycloadditions of dienes 1ij, viith the alkoxy group situated at the allylic position C-6. Nonallylic 4-substituted vinylcyclohexenes 1k-m evolved to ca. 75:25 mixtures of (+)-anti-8k-m and (+)-syn-12k-m derivatives. In all cases, (SS)-(2-p-tolylsulfinyl)-1,4-naphthoquinone reacted from the less hindered face of the more reactive s-cis conformation, giving rise to products in moderate to excellent enantiomeric excesses. Steric effects and torsional interactions in the corresponding approaches account for the observed pi-facial diastereoselectivities at both partners.

  Taxing taxanes: A new method for the preparation of alk‐2‐ene‐1,4‐diols from 1,3‐dienes, especially for geometrical constrained derivatives, via dioxirane derivative formation followed by TiIII‐induced oxirane ring opening, is described. The strategy has been very efficiently implemented to the construction of the 11‐ene‐10,13‐diol moiety present in taxol derivatives.
