Methoxymethylation of Alcohols, Phenols, and Avermectin Aglycones Using MOM-2-pyridylsulfide
摘要:
Methoxymethyl-2-pyridylsulfide (MOM-ON) is an effective methoxymethylating reagent when used in conjunction with AgOTf, NaOAc, and THF. A wide range of MOM ethers are produced from corresponding phenols and alcohols, including tertiary and allylic alcohols, in good yields and under mild, neutral conditions. This method is also effective for the methoxymethylation of avermectin aglycones.

Melamine trisulfonic acid, which is easily prepared by the reaction of melamine with neat chlorosulfonic acid, is able to efficiently catalyze the chemoselective methoxymethylation of alcohols with dimethoxymethane (DMM). All reactions were performed under mild and completely heterogeneous reaction conditions in good to high yields.

used protecting groups for alcohols. This study describes novel direct functionalization of the MOM-protected benzylic alcohols. Preparation of allylic compounds from benzyl MOM ethers was successfully achieved by utilization of allyltrimethylsilane and AlCl3. In addition, direct azidation of benzyl MOM ethers using TMSN3 was successful carried out under AlCl3-mediated reaction conditions. These results
