- Ethyl 3-(2-pyridyl)-2H-azirine-2-carboxylate : synthesis and reactivity with dienesPublication . Alves, Maria José Chão; Fortes, Gil; Lemos, A.; Martins, Cristina I.Ethyl 3-(2-pyridyl)-2H-azirine-2-carboxylate, the first example of an 3-heteroamatic 2H-azirine has been prepared. The reaction of ethyl 3-(2-pyridyl)-2H-azirine-2-carboxylate with conjugated 1,3-dienes, under mild conditions and in the absence of Lewis acid catalyst, afforded cycloadducts in good yield and high stereoselectivity.
