Preparation of 2,3-Dimethyl-5,6-dihydro-4H-1,2-oxaziniumiodide was achieved by N-alkylation of 3-methyl-5,6-dihydro-4H-1,2-oxazine. Reactions with C-nucleophiles led to the corresponding N-methyl-perhydro-1,2-oxazine derivatives. Reaction with sodium hydride in triglyme led to 3-methyl-4-aza-1,3-pentadiene.
通过3-甲基-5,6-二氢-4 H -1,2-恶嗪的N-烷基化来制备2,3-二甲基-5,6-二氢-4 H -1,2-恶唑鎓碘化物。与C-亲核试剂的反应产生相应的N-甲基-过氢-1,2-恶嗪衍生物。在三甘醇二甲醚中与氢化钠反应生成3-甲基-4-氮杂-1,3-戊二烯。
