An efficient method for the direct introduction of alkoxy groups into the β-position of alkene moieties of various α,β-unsaturated carbonyl compounds through the palladium-catalyzed C(sp2)–H monoalkoxylation using alcohols in the presence of sodium nitrite was developed; the corresponding enol ethers were selectively synthesized with minimal generation of acetals.
提出了一种在亚硝酸钠存在下使用醇通过钯催化的C(sp 2)-H单烷氧基化将烷氧基直接引入各种α,β-不饱和羰基化合物的烯烃部分的β位的有效方法; 相应的烯醇醚是用最少的缩醛选择性合成的。
