Microwave-Assisted Synthesis of Tetrahydro-β-carbolines and β-Carbolines

A microwave-mediated Pictet-Spengler procedure utilizing 1,2-dichloroethane (DCE) and trifluoroacetic acid (TFA) was developed to provide tetrahydro-β-carboline salts in high yields. Reactions are complete in 20 minutes or less and the product precipitates from solution in high yields and purity, negating the need for liquid-liquid extraction or column chromatography. This method tolerates a wide range of functionality and can be performed on milligram to gram scales. A subsequent microwave-mediated aromatization of the synthesized tetrahydro-β-carbolines to β-carbolines was also developed utilizing catalytic Pd/C. The aromatization is complete in 60 min or less with most substrates requiring minimal purification. A microwave-assisted Pictet-Spengler procedure was developed to afford tetrahydro-β-carboline salts in high yields with no liquid-liquid extraction or chromatography required. A subsequent microwave-assisted aromatization procedure was also developed to provide β-carbolines in high yields requiring limited purification.

Green synthesis method for beta-carboline heterocyclic compounds

The invention discloses a green synthesis method for beta-carboline heterocyclic compounds. The green synthesis method includes that the beta-carboline heterocyclic compounds are made of alcohols compounds, oxidative condensation, cyclization and re-oxidation one-pot cascade reaction is carried out on tryptamines compounds and alcohol in oxygen under the catalytic effects of catalysts TEMPO and catalysts TBN to obtain the beta-carboline heterocyclic compounds, the reaction temperatures range from 40 DEG C to 120 DEG C, and the reaction time ranges from 6 hours to 48 hours. The green synthesismethod has the advantages that inexpensive, easily available, stable and low-toxicity alcohols which can come from wide sources are used as the raw materials for the beta-carboline heterocyclic compounds, the aerobic oxidative condensation, cyclization and re-oxidation cascade reaction is carried out on the tryptamines compounds and the alcohol under the synergistic catalytic effects of the catalysts TEMPO and the catalysts TBN and acetic acid solvent conditions to prepare the beta-carboline heterocyclic compounds, target products are high in selectivity, a byproduct is water, and accordinglythe green synthesis method is high in efficiency and free of pollution.
