A 5-METHOXYKETOSE has been prepared by the condensation of dioxyacetone, CH2OH.CO.CH2OH, and α-methoxyglyceric aldehyde, CH2OH.CH(OCH3).CHO. The method of synthesis is proof of the position of the methoxyl group and such a structure cannot form a furan ring.
5-甲氧基酮糖是通过二氧
丙酮、CH2OH.CO.CH2OH 和α-甲氧基
甘油醛、CH2OH.CH(OCH3).CHO 的缩合制备的。合成方法证明了甲氧基的位置,这样的结构不能形成
呋喃环。
