Ready conversion of sugar derived 5,6-dihydro-2-pyrones into 3-acyloxy- and 3-acylamido-2-pyrones
5-Acyloxy-5-acyloxymethyl-5,6-dihydro-2-pyrone derivatives (1a, b and 3b and 5-acyloxy-6-methyl-5,6-dihydro-2-pyrone (3a), obtained by acylation of 2-amino-2-deoxy-D-gluconic acid or L-rhamono- and D-glucono-1,5-lactones, react with tin(IV) chloride to give 3-acylamido- and 3-acyloxy-6-acyloxymethyl...

On prolonged reaction time (5 h), the pyrone 4b underwent substitution of the allylic benzoate by chlorine to afford the corresponding 6-chloromethyl derivative 4c. |l eng | |
