The present disclosure relates to methods for treating leukemia, pre-leukemic conditions, as well as myelodysplastic syndrome and acute myelogenous leukemia. The present disclosure further relates to compounds that can be used for treating leukemia, pre-leukemic conditions, as well as myelodysplastic syndrome and acute myelogenous leukemia. The present disclosure also relates to methods for identifying compounds that can be used for treating leukemia, pre-leukemic conditions, as well as myelodysplastic syndrome.

transfer from tert-butyl nitriteundermildconditions and without the use of a catalyst or an additive is reported. This transformation is broadly applicable to the synthesis of furoxans by dimerization and isoxazoles and isoxazolines by cycloaddition. This methodology is also applied for the millimole-scale synthesis of two biologically active compounds. The formation of the nitrile oxide from a diazoacetamide

target for the treatment of, among others, drug-resistant cancers. Although most GPX4 inhibitors rely on a chloroacetamide moiety to modify covalently the protein's catalytic selenocysteine residue, the discovery and mechanisticelucidation of structurally diverse GPX4-inhibiting molecules have uncovered novel electrophilic warheads that bind and inhibit GPX4. Here, we report our discovery that diacylfuroxans

isoxazoles in which the [2 + 1 + 1 + 1] annulation reaction of sulfoxonium ylides is reported for the first time. When the reaction was performed using tBuONO as the nitrogen source without metal catalyst, the desired furoxans were obtained in decent yields with wide substrate scope. Isoxazoles bearing three carbonyl groups were achieved when the reaction was conducted using Cu(TFA)2 as catalyst.
