Palladium-catalyzed acetoxylation of the primary γ-C(sp3)-H bonds in the amino acids Val, Thr, and Ile was achieved using a newly discovered 5-methylisoxazole-3-carboxamide directing group. The γ-acetoxylated α-amino acid derivatives could be e

A novel and efficient protocol for the synthesis of organic ammonium tribromides (OATBs) is developed by using inexpensive and eco-friendly periodic acid as an oxidant for the conversion of Br-to Br3-. The method does not use any mineral acid and metal oxidants. The protocol is utilized to synthesize a new bis(tribromide) viz., 1,1′-(ethane-1,2-diyl)dipiperidinium bis(tribromide) (EDPBT). EDPBT is investigated as a catalyst in the silylation of alcohols and thiols by HMDS (hexamethyldisilazane) under solvent-free conditions.
Properties and reactions of substituted 1,2-thiazetidine 1,1-dioxides: Reactions of 3-acetoxy-β-sultams with sulfur nucleophiles

The acetate moiety of 3-acetoxy-β-sultams 2 is easily displaced by sulfur nucleophiles yielding the alkylthio-β-sultams 3 which are transformed into stable derivatives 4 by silylation. The synthesis of the cephem analogue 7 is described. Reactions of 2 wi
