Abstract
(EN)
Provided are: a cyclic butane compound production method comprising performing a [2+2] photocyclization reaction of an unsaturated compound in the presence of a compound represented by formula 1a or formula 1b; a photosensitizer; and a pyrazole compound. In the formulae, A1, A2, and A4 each independently represent a nitrogen atom or C(R2), each A3 independently represents an oxygen atom, a sulfur atom, or N(R3), each R1 independently represents a hydrogen atom, an alkyl group, an alkenyl group, an aryl group, or a heterocyclic group, and R2 and R3 each independently represent a hydrogen atom or a substituent.
(FR)
L'invention concerne : un procédé de production de composé de butane cyclique comprenant la réalisation d'une réaction de photocyclisation [2+2] d'un composé insaturé en présence d'un composé représenté par la formule 1a ou la formule 1b ; un photosensibilisateur ; et un composé de pyrazole. Dans les formules, A1, A2 et A4 représentent chacun indépendamment un atome d'azote ou C(R2), chaque A3 représente indépendamment un atome d'oxygène, un atome de soufre, ou N(R3), chaque R1 représente indépendamment un atome d'hydrogène, un groupe alkyle, un groupe alcényle, un groupe aryle ou un groupe hétérocyclique, et R2 et R3 représentent chacun indépendamment un atome d'hydrogène ou un substituant.
