概要

• 論文の詳細を見る

• 2-Amino- (<B>2</B>) and 2-hydroxy-1, 3-diazaazulenes (<B>3</B>) underwent smoothly electrophilic bromination under basic conditions to give 2-amino-4,6,8-tribromo- (<B>4</B>) and 6-bromo-2-hydroxy-1,3-diazaazulenes (<B>7</B>), respectively. Bromo derivatives <B>4</B> and <B>7</B> underwent some nucleophilic substitutions, e.g., <B>4</B> reacted with ease with sodium methoxide to give 2-amino-4,6,8-trimethoxy-1,3-diazaazulene (<B>10</B>).
