Directed ortho metalation reactions of aryl O-carbamates; a regiospecific synthesis of 2,2-disubstituted 2H-1-benzopyrans
Chauder,Kalinin,Snieckus
, p. 140 - 144 (2001)
A one-pot regiocontrolled synthesis of 2,2-disubstituted 2H-1-benzopyrans 5 from aryl O-carbamates 4 using the directed ortho metalation reaction is described and constitutes an advantageous complement to classical routes for this class of heterocycles.
