Multicomponent synthesis of benzoxazinones via tandem Ugi/Mitsunobu reactions: an unexpected cine-substitution.
A short (2 steps) synthesis of diverse benzoxazinones by coupling the Ugi multicomponent reaction with an intramolecular Mitsunobu substitution is reported. The cyclization step proceeds via an unexpected cine substitution.
