Ester Glyosylations

Carbohydrates

1)Turning an glycoside into a glycoside w/ ESTER substituents

2)Turning an aldose/ketose glycoside into a glycoside w/ ESTER substituents

Ester Glycosylations

• 1)
  • Requires Initial Glycosylation
  • Sugar-C1-O-R -(NaOH/DMSO)-> 2,3,4,6-tetraSugar-C1-O-R
• 2)
  • Sugar -(Ex (R-CO)2O/Pyridine)-> Sugar-O-CO-R (mutliple O-CO-Rs)
