Synthesis of isoquinoline and yohimbinoid alkaloids
A systematic survey of the different synthetic methodologies available for the syntheses of isoquinoline and yohimbinoid alkaloids revealed that the general approaches to these compounds involved either an A/B C — D/—i E approach or a D/E — C/B/A approach% We have now devised a novel method for the syntheses of both the isoquinoline and indole alkaloids belonging to the tetra— hydroprotoberberi...
متن کاملDesign and Synthesis of Pyrrolo[2,1-a]Isoquinoline-Based Derivatives as New Cytotoxic Agents
A new series of anti-cancer agents based on 1,2-diaryl-5,6-dihydropyrrolo[2,1-a]isoquinoline scaffold containing N,N-diethylaminoethoxy, piperidinylethoxy or morpholinylethoxy group at the para position of the C-2 phenyl ring were synthesized and their cytotoxic activities were assessed against several human cancer cell lines including MCF-7 (ER positive breast cancer cell), MDA-MB231 (ER-ne...

متن کاملSynthesis of 1-substituted 1,2,3,4-tetrahydrobenz[g]isoquinoline-5,10-diones.
1,2-Disubstituted 1,2,3,4-tetrahydrobenz[g]isoquinoline-5,10-diones are prepared for the first time through an activated Pictet-Spengler reaction of the corresponding imines of 2-(1,4-dimethoxynaphth-2-yl)ethylamine in the presence of an acyl chloride and AlCl(3) followed by an oxidation with silver(II) oxide in nitric acid. Depending on the reaction conditions the N-trichloroacetyl protecting ...
متن کاملA simplified and scalable synthesis of artesunate
ABSTRACT An efficient and economically viable approach for the large-scale conversion of artemisinin into the antimalarial frontline drug artesunate was developed. This advanced synthesis includes an NaBH4-induced reduction, followed by an esterification with succinic anhydride under basic conditions. The entire conversion follows the principles of green chemistry, i.e., application of reusable...
