Recent Advances in Stereospecific Transformations of Organoboron Reagents
Enantioenriched boronic esters when activated with organolithiums, can be transformed into boronate complexes that act as chiral organometallic‐type nucleophiles and can engage a wide variety of electrophiles in stereospecific cross‐coupling reactions.

Systematic overview of pyrazole functionalization reactions from C‐5 to N−H. It covers different strategies, from traditional cross‐coupling of prefunctionalized pyrazoles to more efficient direct functionalizations. This review briefly and systematically overviews C–H and N–H functionalization reactions of pyrazoles, aimed at creating new CC and C ...

Development of an Efficient Stereoretentive Para‐Claisen‐Cope Rearrangement
The stereoretentive para‐Claisen‐Cope rearrangement enabled by Europium catalysis is presented, achieving precise phenol functionalization with exceptional chirality transfer under air‐ and moisture‐tolerant conditions. A novel carbonate unlocks superior enantioselectivity in the Tsuji‐Trost allylic alkylation, paving the way for highly enantioenriched

Anionic sigmatropic-electrocyclic-Chugaev cascades: accessing 12-aryl-5-(methylthiocarbonylthio)tetracenes and a related anthra[2,3-b]thiophene [PDF]
1,4-Diols resulting from the double addition of ArCCLi (Ar = Ph, substituted phenyl, 2-thienyl) to ortho-C6H4(CHO)2 undergo cascades to tetracenes on simple admixture of LiHDMS, CS2 and MeI.
