Chemistry of Four-Membered Cyclic Nitrones. 1. Synthesis and Thermal Isomerization of 2,3-Dihydroazete 1-Oxides

Nitroalkenes (1) react with ynamines (1-aminoacetylenes, 2) to yield nitrocyclobutenes 3 and four-membered cyclic nitrones (2,3-dihydroazete 1-oxides, 5); in one case the open-chain isomer (4) of a four-membered cyclic nitrone was isolated.Nitrones 5 isom

(4+2)-CYCLOADDITION OF NITROALKENES WITH YNAMINES; FORMATION OF A 4H-1,2-OXAZINE 2-OXIDE DERIVATIVE

The formation of a thermally unstable (4+2)-cycloadduct, a 4H-1,2-oxazine 2-oxide derivative (1), from the reaction of 1-nitrocyclopentene with 1-phenyl-2-(1-pyrrolidinyl)acetylene has been proven by the structure elucidation of isoxazole derivative 3 whi
