Thermal rearrangement of sugar lactoxime O-vinyl ethers

The thermal reaction of sugar lactoxime O-vinyl ethers gave the corresponding 1,3-oxazoles bearing sugar moiety (ribose, glucose, mannose, and maltose) via a novel rearrangement. The reaction mechanism was briefly discussed.

Thermal Rearrangement of Alkyl O-Vinylcarbohydroximates to 2-Alkyloxazoles

Alkyl O-vinylcarbohydroximates, lactoxime O-vinyl ethers, and sugar lactoxime O-vinyl ethers undergo a novel thermal rearrangement to afford the corresponding 2-alkyloxazoles, 2-(ω-hydroxyalkyl)oxazoles, and oxazoles bearing a sugar moiety, respectively.This rearrangement can also occur under photochemical conditions.
