Phytochemical investigation of barks of Christiana africana led to the identification of cyclopeptide alkaloids, flavonoids, coumarinolignans, iridoids, sesquiterpenoids, and triterpenes. This plant was classified so far in the Tiliaceae family. This

The alkylation of 2-phenyl-4-quinolones was investigated and showed that the N-alkylation versus O-alkylation is highly dependent on whether C-5 is hydroxylated or not. N-Alkylation is favoured by the presence of a 5-hydroxyl group. The synthetic and
