摘要

As shown in Table 1, the formation of PMB ethers using 1 and methyl triflate occurs efficiently on a range of alcohols (depicted in Fig. 2). The presence of magnesium oxide (MgO) provides for higher yields and easier purification of 3. N-Methyl-lepidone (10) is the expected by-product of this reaction; bis-PMB ether 11, presumably derived from adventitious moisture and/or reaction with magnesium oxide, is also observed in varying amounts. ...
