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.
本发明涉及制备花青素的方法,以及制备花青素前体的方法。该方法利用糖与适当的亲电前体之间的偶联反应形成东半部分中间体,然后将其与西半部分中间体反应以形成目标花青素。一些东半部分中间体和亲电前体也是本发明的一部分。
