概要
- 論文の詳細を見る
Reaction of 3-ethyl-5-aryl-1,3,4-oxadiazolium salts (X) with dialkyl acylphosphonates (V) in the presence of triethylamine afforded 2-aryl-4-ethyl-6-alkyl (or aryl)-5,6-dihydro-4H-1,3,4-oxadiazin-5-one derivatives (XII) via an acyclic intermediate (XI) which is a 1 : 1 adduct of X and V. The mechanism of this novel reaction involving ring expansion is discussed briefly.
