Azomethine ylides were generated from Schiffs bases of S-allylcysteine methyl ester and their intramolecular 1,3-dipolar cycloadditions were studied. These reactions led to the synthesis of thieno[3,4b]pyrrole derivatives in good yield.

Generation and cycloaddition of less- or non-stabilized azomethine ylides, or nitrile ylide equivalents, via unprecedented 1,4-stannatropy of N-(tributylstannylmethyl)thioamides were achieved. The reactions with dipolarophiles, such as electron-deficient alkenes and alkynes, afforded corresponding pyrrolidine and pyrrole derivatives effectively.

Herein, we reported the design, synthesis, antitrypanosomal and cytotoxic evaluation of a new phenoxyacetohydrazones series. All derivatives were assayed against bloodstream trypomastigote forms T. cruzi (Y strain) intracellular amastigotes using model L-929 cells infected with trypomastigotes Tulahuen strain. Compound (E)-N′-(3.4-dihydroxybenzylidene)-2-phenoxyacetohydrazide (11) showed activi...
