Abstract
In the synthesis of the main yellow pigment hydroxysafflor yellow A (HSYA), that is present in safflower petals, the key compound 4-(S)-2-acetyl-4,6-di-C-(per-O-acetyl-β-D-glucosyl)-3,4-dihydroxy-5-methoxycyclohexa-2,5-dienone (11b) was diastereoselectively synthesized in an overall yield of 18% from di-C-β-D-glucosylphloroacetophenone per-O-acetate (8).Entities:
