概要
- 論文の詳細を見る
Synthesis of 1-acetonyl-6,7-dimethoxy-3,4-dihydroisoquinoline (IV) was described. On treatment with boiling phosphoryl chloride this underwent a smooth prototropic change to form isoxazole derivative (II) in almost theoretical yield, which had been described previously. Some chemical evidence in support of the structure of (II) was also provided.
