Abstract

Allyl pyridyl ethers are important intermediates in organic synthesis, which could be accessed by Williamson or SNAr-type etherification. While Williamson etherification has been well studied, the SNAr-type reaction remains less explored. In this paper, a series of allyl pyridyl ethers were synthesized via transition metal-free SNAr-type etherification with different allyl alcohols in good yields. The poor-yielding etherification for cinnamyl alcohol was finally optimized to 82% yield with a molecular sieve as the additive.
