studied. The annulation of certain hindered propargylic alcohols affords 1,3-benzoxazinederivatives, rather than the expected 2-aminonaphthalenes. The involvement of trialkylamine bases in the formation of these heterocyclic compounds has been established. A proposed mechanism for the synthesis of 1,3-benzoxazinederivatives involves the formation of the expected 2-amino-3-(1-hydroxyalkyl)naphthalenes
