• Photochemical behaviour of 3.4-epoxyprecocene-I and related epoxychromans
  作者：G. Ariamala、K.K. Balasubramanian

  日期：1989.1

  A systematic study of photochemical behaviour of 3,4-epoxyprecocene-I and related epoxychromans was undertaken. Upon irradiation in acetone or cyclohexane, 3,4-epoxyprecocene-I was found to undergo photoisomerisation to the corresponding 3-chromanone . In contrast, the photochemical behaviour of analogous 3,4-dihydro-3,4-epoxy-2H-1-benzopyrans 3 was found to be dependent upon the nature of solvent

  进行了系统的研究3,4-epoxyprecocene-I和相关的环氧chromans的光化学行为。在丙酮或环己烷中辐照后，发现3，4-环氧前十烯-1经历光异构化为相应的3-苯并二氢吡喃酮。相反，发现类似的3，4-二氢-3，4-环氧-2H-1-苯并吡喃3的光化学行为取决于溶剂的性质。在环己烯中辐射3导致光脱羰基化导致2,3-二氢苯并呋喃的形成，而在丙酮中辐射导致chramanones的形成。
