A synthesis of 2-aza-l,3-butadienes 3 substituted with a phosphonate group in the 3-position is described. The key step is the olefination reaction of bisphosphonylalkyl imino compounds 2, with aldehydes in the presence of base. Heterocyclisation of 2-azatrienes 5 afforded substituted 2-phosphorylat
Aza-Wittig reaction of N-acrylic phospha-x5-azenes with aldehydes gives 3-ethoxycarbonyl 2-aza-1,3-dienes in very high yields. Compounds containing the 2-aza-1,3-diene group represent a very important class of derivatives as a result of their potential as key intermediates in organic synthesis. Part
