Title
(EN) N-ALKYLATION OF ACRIDANS
(FR) N-ALKYLATION D'ACRIDANES
Abstract
(EN)
The present invention provides compounds used in the synthesis of chemiluminescent acridinium compounds and methods of producing these compounds. Specifically, methods are provided for the N-alkylation of acridan compounds using alkylating reagents. Typically, these alkylating reagents comprise a protected sulfonate group protected with an acid-labile protecting group.

La présente invention concerne des composés utilisés dans la synthèse de composés d'acridinium chimioluminescents et des procédés de production de ces composés. De façon spécifique, l'invention concerne des procédés pour la N-alkylation de composés acridane à l'aide de réactifs d'alkylation. Typiquement, ces réactifs d'alkylation comprennent un groupe sulfonate protégé par un groupe protecteur labile en milieu acide.
