2-甲基重氮萘醌在环醚中光解产物的2D NMR研究

2D NMR STUDY ON PHOTOLYSTIC PRODUCTS OF 2-METHYL-NAPHTHOQUINONE DIAZIDE IN CYCLIC ETHERS

应用二维核磁共振对２－甲基重氮萘醌在四氢呋喃和二氧六环中光解反应的产物：２－甲基－４－螺（２’－四氢吡喃）萘－１－酮（３）、２－甲基－４－（２’四氢呋喃基）－１－萘酚（４）、２－甲基－４－螺［７’－（１’，４’－二氧杂环庚烷）萘－１－酮（５）、２－甲基－４－［２’－（１’，４’－二氧杂环己基）］－１－萘酚（６）和二（２－甲基－萘－２２－冠－６）（７）的１Ｈ和１３Ｃ ＮＭＲ谱进行了全归属．

Photolysis of 2-methyl-naphthoquinone diazide produced 2-methyl-4-spiro(2'-te- trahydro-pyran) naphthalenone (3) and 2-methyl-4-(2'-tetrahydrofuran) naphthol (4) in tetrhydrofuran, and 2-methyl-4-spiro [7'- (1' 4'-dioxaheptane)] naphthalenone (5), 2- methyl-4- (2'- dioxanyl) naphthoL (6) and bis (2-methyl-1, 4-naphthalene) 22-crown-6 (7) in dioxane. The structures of these compounds were elucidated by 2D NMR spectroscopy and their 1H and 13C NMR spectra were totally assigned.
