Under control: A formal [4+1]/[3+2] cycloaddition cascade of sulfurylides and alkene‐tethered nitroolefins has been developed, and provides an efficient synthesis of fused polycyclic heterocyclic compounds in good to excellent overall yields with excellent diastereocontrol (see scheme). A catalytic asymmetric variant of this reaction has also been disclosed.
A highly efficient and enantioselectiveintramolecularcrossedRauhut–Currier (RC) reaction of nitroolefins with tethered enonates has been developed throughcooperativenucleophilicactivation and a hydrogen‐bonding catalytic strategy (≤98 % ee and 98 % yield). The reaction features simple experimental procedures and is completely chemoselective and atom‐economic in character. The potential synthetic
