Sulfur Ylides in Skeletal‐Editing—Ring Expansion Reactions

Helvetica Chimica Acta, Volume 109, Issue 3, March 2026.
Sulfur ylides (S‐ylides) are emergent diazo surrogates that enable skeletal editing and ring expansion with safer handling and broad functional group tolerance. This perspective covers pioneer works and highlights recent advances in the field, while outlining key challenges and future directions that may redefine the role of S‐ylides in modern ...

1,3-Dipolar Cycloaddition Reactions of Azomethine Ylides with Carbonyl Dipolarophiles Yielding Oxazolidine Derivatives

Molecules, 2016
We provide a comprehensive account of the 1,3-dipolar cycloaddition reactions of azomethine ylides with carbonyl dipolarophiles. Many different azomethine ylides have been studied, including stabilized and non-stabilized ylides.

Synthesis of α‐Pentafluorosulfanylated‐β2,3‐Amino Esters

ChemistryEurope, Volume 4, Issue 2, February 2026.
De novo α‐SF5‐β2,3‐amino esters are now accessible through a straightforward aza‐Michael reaction using a series of newly developed (E)‐α‐SF5‐α,β‐unsaturated esters. Two new, highly functionalized, contiguous tertiary stereocenters are formed with diastereodivergence governed by the choice of solvent and/or base.

The regioselective synthesis of spirooxindolo pyrrolidines and pyrrolizidines via three-component reactions of acrylamides and aroylacrylic acids with isatins and α-amino acids

Beilstein Journal of Organic Chemistry, 2014
The regioselective three-component condensation of azomethine ylides derived from isatins and α-amino acids with acrylamides or aroylacrylic acids as dipolarophiles has been realized through a one-pot 1,3-dipolar cycloaddition protocol.
