Abstract (en)
[origin: WO8401577A1] A process for preparing a cycloaddition compound, which comprises reacting ketene with a carbonyl group-containing compound having formula (I), which contains a highly electron-attractant group in the alpha -position relative to the carbonyl group in the presence of a chiral tertiary amine as catalyst to form a cycloaddition compound having formula (II).
Abstract (fr)
Un procédé de préparation d'un composé de cyclo-addition comprend la réaction d'un cétène avec un composé contenant un groupe carbonyl de formule (I) et comportant un groupe attirant fortement les électrons en position alpha par rapport au groupe carbonyl en présence d'une amine tertiaire chirale en tant que catalyseur pour former un composé de cyclo-addition de formule (II).
