Ethyl 2-(Diisopropoxyphosphoryl)-2H-Azirine-3-Carboxylate: Reactions with Activated 1,3-Butadienes

The 12th International Electronic Conference on Synthetic Organic Chemistry session General Organic Synthesis Ethyl 2-(diisopropoxyphosphoryl)-2H-azirine-3-carboxylate was generated “in situ” and reacted with a number of 1,3-butadienes. Cycloadducts, or in one case an ensuing rearranged product, were isolated with moderate to good yields The authors thank Fundação para a Ciência e Tecnologia, CIQA-Centro de Investigação em Química do Algarve and Xunta de Galicia for financial support under project 07CSA008203PR
