Acridine derivatives

An Efficient and Simple Aminobenzannulation Reaction: Pyrrolidine as a Trigger
the Synthesis of 1-Amino-acridines. — The methodology needs only molecular
37- 143 for
sieves for the enamine synthesis step in the case of pyrrolidine (IIa). In other cases
Al2O3 or PtCl2 are required to catalyze the reaction. When diethylamine is used as the
amine substrate, the reaction stops at the enamine stage. Furthermore, a new acridine
derivative (IX) bearing a sensitive protective group is obtained in good yield. —
