Beschreibung
Zusammenfassung:	This invention relates to the functionalized cyanine dyes and more particularly, to the synthesis of chiral 3-substituted 2,3'-dymethyl-3H-indole and its derivatives as intermediates for preparation of cyanine dyes, to methods of preparing these dyes and the dyes so prepared. Cette invention porte sur des colorants de cyanine fonctionnalisés et, notamment, sur la synthèse de 2,3'-diméthyl-3 H -indole chiral substitué en position 3 et sur leurs dérivés utiles comme intermédiaires dans la préparation de colorants de cyanine, ainsi que sur des procédés de préparation de ces colorants et sur les colorants ainsi obtenus.
