Abstract

The invention provides a high-selectivity synthesis method of a compound, namely 1,3,3-trimethyl-2-oxabicyclic[2,2,2]octane, as shown in the formula (I). The method is high in selectivity and high inconversation rate; the catalyst can be recycled; and the method is safe, environment-friendly, simple and convenient in operation and suitable for industrialized mass production.

Description

Technical field [0001] The present invention relates to a highly selective synthetic compound of formula (I) 1,3,3-trimethyl-2-oxabicyclo[2,2,2]octane [hereinafter sometimes referred to as 1,8-cineole] Methods. [0002] Background technique [0003] 1,8-Cineole (1,8-Cineole), chemical name 1,3,3-trimethyl-2-oxabicyclo[2,2,2]octane, is a monoterpenoid , It is a colorless transparent liquid with camphor smell and cool herbal taste. It is the main component of eucalyptus oil. It is mainly found in the Myrtaceae plant Eucalyptus globulus and Lauraceae camphor tree. It has the effect of dispelling wind and relieving pain. As an important fine chemical product, it is widely used in industrial production fields such as medicine, flavors and fragrances. [0004] At present, most of the domestic use natural extraction methods to prepare 1,8-cineole, but natural plant resources are limited, the output of 1.8-cineole is difficult to meet market demand, and the extracted eucalyptus oil conta...
