  Stereocontrolled intramolecular meta-arene–alkene photocycloaddition reactions using chiral tethers: efficiency of the tether derived from 2,4-pentanediol

  摘要：

  Photochemical reactions of substrates consisting of phenyl and vinyl groups, which are tethered with a chiral diol, resulted in intramolecular meta-arene-alkene cycloaddition; the reaction efficiency as well as the stereoselectivity was studied. 1,3-Butanediol, 2-substituted 1,3-propanediols, 2-methyl-2,4-penetanediol, and 2,6-dimethyl-3,5-heptanediol were employed as tethers, and the results are compared with those obtained with 2,4-pentanediol (PD) tether, which are known to show high stereoselectivity and moderate efficiency. All the reactions with the lower analogues were less efficient than with PD, although one of the butanediol-tethered reactions afforded a single stereoisomer as PD did. The dimethylheptanediol tether showed similar efficiency but lower stereoselectivity than PD. The results suggest that the PD tether has an optimized structure having a proper flexibility.

• Regio- and diastereo-chemically controlled photocycloaddition of an arene and an alkene linked by a chiral auxiliary

  Intramolecular meta-arene-alkene photocycloaddition of 1b, the substrate having a chiral auxiliary as a linking bridge between the arene and the alkene, resulted in high diastereofacial differentiation of the alkene at the addition step and sufficient regiocontrol of the subsequent ring closure step to give a single diastereomer 4.
