In amoebic allure a methylthiomethyl (MTM) ether is a careful accumulation for hydroxyl groups. Hydroxyl groups are present in abounding actinic compounds and they accept to be adequate during oxidation, acylation, halogenation, aridity and added reactions to which they are susceptible.
Many kinds of careful groups for hydroxyl groups accept been developed and acclimated in amoebic chemistry, but the amount of careful groups for tertiary hydroxyl groups, which are affected to acid-catalyzed dehydration, is still baby because of their poor reactiveness. They can be calmly adequate with MTM ethers and recovered in acceptable yield.
To acquaint an MTM ether to a hydroxyl group, two methods are mainly used. One is a archetypal Williamson ether amalgam application an MTM halide as an MTM ability and sodium hydride (NaH) as a base. The added is a appropriate method, in which dimethyl sulfoxide (DMSO) and acerb anhydride (Ac2O) are used. In this case, the acknowledgment gain with Pummerer rearrangement:
Methylthiomethyl (MTM) ethers accept addition advantage. They are removed by aloof (but toxic) mercuric chloride, to which a lot of added ethers are stable. As a result, the careful deprotection of polyfunctional molecules becomes accessible application MTM ethers as the careful groups for their hydroxyl groups.
