Abstract: The use of readily accessible ammonium ylides for (asymmetric) transformations, especially cyclization reactions, has received considerable attention over the past two decades. A variety of highly enantioselective protocols to facilitate annulation reactions have recently been… read more here.

DOI: 10.1021/acs.orglett.7b03953
Abstract: N-Sulfonylhydrazones generate sulfinates selectively when treated with a stabilized Wittig ylide in a polar aprotic solvent at elevated temperature. The transition metal and base free decomposition method is applicable to N-sulfonylhydrazones generated from a number… read more here.

Abstract: Abstract The stereoselective syntheses of novel trans-5-aroyl-2,4-diaryl-4,5-dihydrofuran-3-carbonitriles have been achieved via a one-pot, three-component tandem protocol involving aroyl acetonitriles, aromatic aldehydes, and imidazolium ylide in the presence of Et3N.
