Aldehydes and ketones are readily converted into the corresponding 1,3-dioxanes by treatment with 2-(2-pyridyl)propane-1,3-diol. The protective group is easily removed under mild conditions after activation by quaternization with methyl iodide.
通过用2-(2-吡啶基)丙烷-1,3-二醇处理,可以容易地将醛和酮转化为相应的1,3-二恶烷。保护基团在活化后通过甲基碘季铵化可在温和条件下轻松去除。
