Abstract
The aglycone glycitein (1) of the title glucoside glycitin (2) was pre pared by oxidative rearrangement of the fully protected chalcone 4 by Tl(NO3)(3) in MeOH into 5 followed by deprotection and ring closure. I ts glucosylation with alpha-acetobromoglucose and subsequent saponific ation gave 2 as the main product.
