Paragraph 0068-0070; 0072-0074, (2017/02/28)
The invention provides a synthetic method of asymmetrical ether in the field of organic synthesis. The general equation of reaction is defined in the specification. In the equation, R-OH is benzyl alcohol, p-methoxy benzyl alcohol, tert-butyl alcohol, diphenyl carbinol or triphenylmethanol; and R'OH is common alkyl alcohol or a compound containing hydroxyl groups. A gold catalyst required by the reaction is Ph3PAuCl, Ph3PAuNTf2, HAuCl4, NaAuCl4, Ph3PAuOTf, Ph3PAuSbF6, IPrAuCl or nano-gold. A medium required by the reaction is solvent-free, and is toluene, mesitylene, 1,2-dichloroethane, tetrahydrofuran, acetonitrile or acetone. The reaction is implemented by heating through a microwave reactor. The method has advantages as follows: raw materials are easily available; operation is simple; the range of application is wide; atom economy is good; and the reaction is green.

A microwave-irradiated alcohol-protecting strategy based on gold catalysis utilizing benzyl alcohol, tert-butyl alcohol and triphenylmethanol as alkylating reagents has been developed. This protecting strategy has wide functional group tolerance with satisfactory yields for the majority of the selected alcohols. The mechanism of this transformation was probed with oxygen-18 isotope labelled alcohols assisted by GC-MS techniques and chemical kinetic experiments. This strategy provides an efficient, straightforward and alternative approach to the preparation of benzyl, tert-butyl and trityl ethers in organic synthesis.
