Diastereoselective synthesis of potent antimalarial cis-β-lactam agents
Fifteen novel β-lactams bearing the N-ethyl tert-butyl carbamate group 5a-o and fifteen N-(2-aminoethyl) β-lactams 6a-o were synthesized by the ketene-imine [2+2] cycloaddition reaction (Staudinger ). The cycloaddition reaction was found to be totally diastereoselective leading exclusively to the formation of the cis-β-lactam derivatives. These newly synthesized β-lactams were evaluated for the...

متن کاملCryptolepine and development of new antimalarial agents
Natural product-derived drugs exemplified by quinine, isolated from South American Cinchona species and artemisinin discovered in China are of immense importance for the treatment of malaria. Although malaria parasites resistant to artemisinin have not yet been found in malaria patients, the need for new antimalarial agents remains. The burden of malaria is heaviest in Africa where over a milli...

متن کاملEnantioselective synthesis of encecaline-derived potent antimalarial agents.
The high antiplasmodial activity of racemic benzylamines rac-1 and rac-2 stimulated the synthesis of pure enantiomers. Ellman's chiral sulfinamides (S)-6 and (R)-6 were used as chiral auxiliaries. Condensation of prochiral ketone 5 with enantiomerically pure sulfinamides (S)-6 and (R)-6 and subsequent NaBH4 reduction provided predominantly unlike configured diastereomers (S,R)-8 and (R,S)-8 (ra...
