Title (EN) TRICYCLIC TETRAHYDROFURAN LACTONE DERIVATIVES AND PROCESS FOR THE PREPARATION THEREOF
(FR) DÉRIVÉS TRICYCLIQUES DE LACTONES DU TÉTRAHYDROFURANE ET PROCÉDÉ POUR LA PRÉPARATION DE CEUX-CI
Abstract: front page image
(EN)The present invention relates to tricyclic tetrahydrofuran lactone derivatives and a preparation method thereof. Particularly, the present invention relates to a process of preparing the above compounds 'tetrahydrofuran lactone derivatives' by performing an intramolecular cyclization of tetrahydrofuran-allenic acid derivatives in the presence of a phenyl halide, a palladium catalyst and a base.
(FR)La présente invention concerne des dérivés tricycliques de lactones du tétrahydrofurane et un procédé de préparation de ceux-ci. En particulier, la présente invention concerne un procédé de préparation des composés 'dérivés de lactones du tétrahydrofurane' ci-dessus en effectuant une cyclisation intramoléculaire de dérivés d'acide tétrahydrofuran-allénique en présence d'un halogénure de phényle, d'un catalyseur à base de palladium et d'une base.
