The present invention relates to methods of preparing anthocyanins, and methods of preparing precursors of anthocyanins. The methods utilise a coupling reaction between a sugar and a suitable electrophilic precursor to form Eastern half intermediates that are then reacted with Western half intermediates to form the target anthocyanins. Some Eastern half intermediates and electrophilic precursors also form part of the invention.

[FR] La présente invention concerne des procédés de préparation d'anthocyanines et des procédés de préparation de précurseurs d'anthocyanines. Les procédés utilisent une réaction de couplage entre un sucre et un précurseur électrophile approprié de manière à former des intermédiaires de la moitié droite, qui sont ensuite mis à réagir avec des intermédiaires de la moitié gauche pour former les anthocyanines cibles. Quelques intermédiaires de la moitié droite et précurseurs électrophiles font également partie de l'invention.
