enantioenriched substituted quinolizidines has been achieved by chiraldirhodium(II) carboxylate-catalyzed dearomatizing formal [3 + 3]-cycloaddition of isoquinolinium/pyridinium methylides and enol diazoacetates. Coordination of Lewis basic methylides to dirhodium(II) prompts the rearrangement of the enol-carbene that is bound to dirhodium to produce a donor-acceptor cyclopropene. The donor-acceptor

Alkylation of acylated quinolines and isoquinolines with alkenyl boron-“ate” complexes via 1,2-metalate rearrangement gives substituted, dearomatized nitrogen heterocycles with high diastereocontrol. The modularity of this multi-component coupling allows for facile access to a range of valuable nitrogen-containing scaffolds. This one-pot protocol installs a chiral boronic ester moiety which can be
A (3+2) cycloaddition of heteroaromatic N-ylides with sulfenes, which are generated in situ from sulfonyl chlorides, has been developed. A variety of ylides were transformed into the corresponding sulfone-embedded N-fused heterocycles in high yields. Hexafluoroisopropyl mesylate was demonstrated to be a suitable reactant for quinolinium ylides. Furthermore, this cycloaddition could be performed with
