A method of forming a cyclopropane having enhanced chirality said method comprising reacting together (1), a symmetrical 1,2-dioxine of the formula (1), wherein X and Y are the same and are groups in which a carbon atom is bonded to the dioxine backbone; and a phosphorus ylide or a phosphorus ylide precursor; in the presence of a cobalt catalyst containing a chiral ligand.
L'invention concerne un procédé de formation d'un cyclopropane ayant une chiralité améliorée et consistant à faire réagir: une 1,2-dioxine symétrique de formule (1), dans laquelle X et Y sont identiques et désignent des groupes dans lesquels un atome de carbone se lie à un squelette de dioxine; et un ylide phosphoré ou un précurseur ylide phosphoré en présence d'un catalyseur de cobalt contenant un ligand chiral.
