摘要：

The reaction of the quinisatin-aminals 1, 2, and 10 with phenol in acetic acid in the presence of H2SO4 gives the carbinols 5, 6 and 12., These compounds are reduced with Zn/HCl to yield 4-hydroxy-3-p-hydroxyphenyl-2-quinolones (7, 8, and 13). The condensation of quinisatin-hydrate 3 with ethyl malonate to 15 is catalyzed with morpholine. The reaction of 3 with 2-picoline gives 17. © 1969 Springer-Verlag.
