查询词典 direct method

An improved Adler method was used for preparing TAPPH〓. TAPPH〓 was synthesized in high yield by direct condensation of pyrrole with 4aminobenzaldehyde in refluxing propanoic acid with the presence of vitamin C. This new synthetic strategy for preparing TAPPH〓 can greatly extend synthetic methods for porphyrins containing amino groups.
