Summary: Pyrroloimidazoles have been synthesized by diastereoselective of 1,3-dipolar cycloaddition by using 4, 5-dihydroimidazolium ylides
with an alkylating agent and base.

In recent years, we have endeavored to expand the synthesis of phosphorous ylides
along with developing experimental and theoretical studies on the kinetics and mechanisms of these reactions [29-36].
Pecharsky points out another intriguing difference between conventional solvent-based ylide
generation and ball-milling: the bases required for each process.

A small sample of the individual chapter topics includes arborescent polymers with a mesoscopic scale, living polymerization of ylides
, highly branched functional polymer architectures using click chemistry, and precision polyolefins.
In this work, they present 13 review articles describing various aspects of this emerging field, including asymmetric synthesis of chiral sulfoxides, asymmetric synthesis of optically active sulfinic acid esters, asymmetric transformations mediated by sulfinyl groups, synthesis and applications of chiral dithiocetal derivatives, synthesis and use of chiral sulfur ylides
, synthesis and use of chiral sulfoximines, synthesis and use of chiral sulfinamides, asymmetric catalysis using sulfoxides as ligands, sulfones in asymmetric catalysis, and computational studies on asymmetric reactions with sulfur reagents.
