Unprecedented chemodivergent Staudinger reactions of secondary phosphine oxides (SPO) have been developed. Reagent-controlled 1- or 2-nitrogen atom exclusions from azides have been achieved. Conversion of a chiral SPO to a phosphinic amide was stereoretentive, and the potassium salt of natural product LL-D05139β was synthesized for the first time.
biosynthesis. Structure‐based virtual screening of about 3 000 000 commercially available compounds against the crystal structure of the glycosyltransferase (GT) domain of the Staphylococcus aureus penicillin‐binding protein 2 (S. aureus PBP2) resulted in identification of an isatin derivative, 2‐(3‐(2‐carbamimidoylhydrazono)‐2‐oxoindolin‐1‐yl)‐N‐(m‐tolyl)acetamide (4) as a novel potential GT inhibitor.
