Six monoprotected acetals and -thioacetals of glutaradehyde and its symmetrical dimethyl derivatives were synthesized. Microwave-assisted heating proved to be a substantially more selective method for monoprotection than conventional heating. All reactions were efficient and only traces of diprotected material were formed.
合成了六种戊二醛的单保护缩醛和-硫缩醛及其对称的二甲基衍生物。事实证明,微波辅助加热是一种比传统加热更具选择性的单保护方法。所有反应都是有效的,并且仅形成痕量的双保护材料。
