Thermal Behavior of Head-to-head Coumarin Dimers and Their Lactone-opened Derivatives

The thermal behavior of head-to-head coumarin dimers and twelwe lactone-opened derivatives was investigated.Though the lactone rings in coumarin dimers are very susceptible to nucleophilic ring-opening, heating these derivatives reformed six-membered lactone rings except for certain imide and diamide derivatives.The large neiboring group effect allowed the relactonization by the attack of hydroxyphenyl group to carbonyl carbon in preference to the scission of cyclobutane ring.

Symmetric and Asymmetric Photocleavage of the Cyclobutane Rings in Head-to-head Coumarin Dimers and Their Lactone-opened Derivatives

The photochemical behaviour of fifteen derivatives of head-to-head coumarin demers has been investigated.The photocleavage of the cyclobutane rings in these compounds in solution occurs on irradiation with light of wavelenght 277 +/- 10 nm to give two molecules of coumarin derivatives via symmetric fission and/or 2,2'-dihydroxystilbene and fumaric (and maleic) acid derivatives via asymmetric fission.The direction of these photofissions is primarily affected by the basic structure of the coumarin dimer derivative, the photocleavage proceeding exclusively with retention of the ring structure when the derivative has a stable five- or six-membered ring fused to its cyclobutane ring.A secondary influence is the steric repulsion between the substituents attached to the cyclobutane ring.

REACTION OF SYN HEAD-TO-HEAD COUMARIN DIMER WITH AMINES AND THERMAL BEHAVIOR OF THE ADDUCTS

The lacton-opening reaction of syn head-to-head coumarin dimer with amines gave c-3,c-4-bis(2-hydroxyphenyl)-r-1,c-2-cyclobutanedicarboxamides and/or -dicarboximides.The product ratio of the amide to the imide varied with the reaction temperature and the amount of amine used.Thermal reaction of these lactone-opened derivatives proceeded in two ways depending on the nature of amine moiety to give either the original coumarin dimer or 2,2'-dihydroxystilbene and the maleimide derivative.
