A Regiospecific Synthesis of Highly Substituted Acridones
Mongrain, Colette,Brassard, Paul
, p. 2109 - 2128 (2007/10/02)
The regiospecific substitution of isomeric halogenoquinones by the appropriate sulfonamide can be carried in the presence of fluoride ions and affords the corresponding o-methoxycarbonylanilinoquinones of definite structure.After reductive methylation, sa
