  Asymmetric induction in an intramolecular [2+2] photocycloaddition within chirally modified zeolite supercages

  摘要：

  Photoirradiation of 1-cyano-2-(5-methyl-2-oxa-4-hexenyl)naphthalene, included in NaY zeolites along with chiral inductors, such as diethyl tartrate or phenylalaninol, gives an intrarnolecular [2+2] photocycloadduct with a maximum 15% ee. The degree of enantioselectivity was found to depend on the Si/Al ratio, the nature of the cations in the zeolites, the structure of the chiral inductors, and the molar ratio of substrate and chiral inductors.

  Irradiation of 2,3-dimethylbut-2-enyl 1-cyano-2-naphthylmethyl ether in the presence of Eu(hfc)3 in benzene site-selectively afforded the (2π + 2π) intramolecular photocycloadduct at the 1,2-position on the naphthalene ring. On the other hand, allyl 1-cyano-2-naphthylmethyl ether in the presence of Mg(ClO4)2 in acetonitrile gave the photocycloadduct at the 3,4-position as a sole product.

  在苯中，2,3-二甲基-2-丁烯基1-氰基-2-萘甲基醚在Eu(hfc)3的存在下，择位选择性地生成了萘环1,2-位的(2π + 2π)分子内光环加成产物。另一方面，丙烯基1-氰基-2-萘甲基醚在醋腈中加入Mg(ClO4)2，仅生成3,4-位的光环加成产物。

  Intramolecular [2+2] and [2+3] photocycloadditions of 2-(2-alkenyloxymethyl)naphthalene-1-carbonitriles and their photocycloreversion using glass-made microreactors were investigated in comparison with photoreactions under conventional batch conditions. Both the efficiency and regioselectivity were improved by use of glass-made microreactors. These results can be explained by thorough absorption of light and outflow of primary product from the reaction system.

  The intramolecular photocycloaddition of a 1-cyanonaphthalene derivative in microreactors made of poly(dimethylsiloxane) (PDMS) was examined. By using the microreactors and flow system, both the efficiency and regioselectivity increased compared with those under batch conditions.
