NovelN-transfer reagent for converting α-amino acid derivatives to α-diazo compounds

A novel universalN-transfer reagent for direct and effective transformation of α-amino ketones, acetamides, and esters to the corresponding α-diazo products under mild basic conditions has been developed. This one-step synthetic approach not only allows for generation of α-substituted-α-diazo carbonyl compounds from α-amino acid derivatives but also permits preparation of α-diazo dipeptides fromN-terminal dipeptides (32 examples, up to 91%).

One-pot synthesis of trans-β-lactams from ferrocenylketene generated by thermal Wolff rearrangement

A series of β-lactams containing the ferrocene moiety were synthesized through the Staudinger reaction between ferrocenylketene generated by the thermal Wolff rearrangement of the corresponding diazo ketone and various imines. The stereochemical outcome h

An efficient PEG-400 mediated catalyst free green synthesis of 2-amino-thiazoles from α-diazoketones and thiourea

A simple and efficient method has been developed for the synthesis of 2-aminothiazoles from α-diazoketones using PEG-400 solvent system. This novel synthetic approach involves the reaction between thiourea and α-diazoketones in PEG-400 at 100 °C to yield the corresponding 2-aminothiazoles in good yields. The method is simple, rapid and generates thiazole derivatives in excellent yields without the use of any catalysts. This green protocol can be utilized for fast synthesis of various 2-aminothiazoles in good yields. [Figure not available: see fulltext.]
