Pyrrolo-[1, 2-a] imidazoles have been synthesized by diastereoselective of 1,3dipolar cycloaddition by using 4, 5-dihydroimidazolium ylides with an alkylating agent and base or more recently carbenoid insertion to dihydroimidazoles.
Azomethine ylides have been used as 1, 3dipoles in cycloaddition reactions for the formation of five-membered rings containing nitrogen atom in the ring focused to substantial attention.
Free and supported phosphorus ylides
as strong neutral Bronsted bases.
Mechanically induced solid-state generation of phosphorus ylides and the solvent-free Wittig reaction.
The team created the ylide (benzoylmethylene) triphenylphosphorane by ball-milling (phenacyl) triphenylphosphonium bromide with anhydrous potassium carbonate ([K.
