first asymmetric total synthesis of synerazol, an antifungal antibiotic, has been accomplished, allowing determination of its absolute stereochemistry. A more practical second generation route was also established. The key steps are racemization-free deprotection of a TIPS group and introduction of a methyl ether by DMD oxidation of the benzylidene moiety in a substrate having a small protecting group
A concise synthetic approach to mugineic acid and 2’-hydroxynicotianamine was established. Unlike all other synthetic methods, this approach utilized epoxidering-openingreactions to form two C−N bonds without redox reactions. Mugineic acid was synthesized on a gram scale, and the dansyl-labeled nicotianamine (NA) iron complexes were taken up by oocytes overexpressing transporters ZmYS1 (from maize)

Irreversible EGFR inhibitors can circumvent acquired resistance to first-generation reversible, ATP-competitive inhibitors in the treatment of non-small-cell lung cancer. They contain both a driver group, which assures target recognition, and it warhead, generally an acrylamide or propargylamide fragment that binds covalently to Cys797 within the kinase domain of EGFR. We performed it systematic exploration of the role for the warhead group, introducing different cysteine-trapping fragments at position 6 of a traditional 4-anilinoquinazoline scaffold. We found that different reactive groups, including epoxyamides (compounds 3-6) and phenoxyacetamides (compounds 7-9), were able to irreversibly inhibit EGFR. In particular, at significant lower concentrations than gefitinib (1), (2R,3R)-N-(4-(3-bromoanilino)quinazolin-6-yl)-3-(piperidin-1-ylmethyl)oxirane-2-carboxamide (6) inhibited EGFR autophosphorylation and downstream Signaling pathways, Suppressed proliferation, and induced apoptosis in gefitinib-resistant NSCLC H 1975 cells, harboring the T790M mutation in EGFR.
