The reaction of acids, alcohols, acylamides, 1,2-diols, 1,2-diamines or amino alcohols with activated alkynes catalyzed by 1,4-diazabicyclo[2.2.2]octane (DABCO) was systematically investigated. A series of unsaturated alkenoic acid esters or heterocycles were formed in the reaction of monobasic or dibasic nucleophiles in excellent yields, respectively.
系统地研究了酸,醇,酰基酰胺,1,2-二醇,1,2-二胺或氨基醇与1,4-二氮杂双环[2.2.2]辛烷(DABCO)催化的炔烃的反应。在一元或二元亲核试剂的反应中,分别以优异的收率形成了一系列不饱和链烯酸酯或杂环。
