The novel methods for the synthesis of Camptothecin intermediates were described as Friedlandle. Second, we synthsized the key compound—BI, and then made some improvements and innovations of the methods from the reference. The method of using more economically phenylaldehyde derivatives and phenylamine derivatives instead of o-aminobenzaldhyde was worked out.
