- 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.

- Process for the preparation of organo N-hydroxyimidates
-
Organo N-hydroxyimidates are prepared by reacting an organonitrile with an organic alcohol and with a hydrogen halide, in the presence of an organic solvent (which may include an excess of the organonitrile reactant), under anhydrous conditions, to form the corresponding organoimidate hydrohalide, and then reacting said organoimidate hydrohalide with a hydroxylamine salt and ammonia gas in the presence of an organic solvent (which can be the excess organonitrile from the first step), under anhydrous conditions, to produce the corresponding organo N-hydroxyimidate.
