Synthesis of thromboxane A2 models from glucose
Trans-opening of the 2,3-anhydro-6-deoxy-4-O-methyl-α-D-allopyranoside with lithium bromide yields the altro and gluco regioisomers methyl 2-bromo- 2,6-dideoxy-4-O-methyl-α-D-altropyranoside and methyl 2-bromo-3,6-dideoxy- 4-O-methyl-α-D-glycopyranoside which can be hydrolysed to give the sugar prec...
