Methanolysis of an anhydro acetal
= Methanolysis of an anhydro acetal
<acid (chemistry)> activation can cleave an anomeric <acetal> bridge, producing an <oxocarbenium>-like <electrophile> and a free <alcohol> on the former tether. <methanol> capture produces a methyl <acetal>; anomeric <stereochemistry> and chair preference must be distinguished.
