still elusive in most cases. Herein, we report a designing approach to enable selective nitrenoid transfer leading to sp2 spirocyclization and sp3 C-H insertion by cooperative two-point modulation of ligands in the CpXIr(III)(κ2-chelate) catalyst system. Computational analysis led us to interrogate structural motifs that can attribute to the desired mechanistic dichotomy. Multivariate linear regression
transmission along the aromatic system, thus enabling dynamickineticresolution via a traditional reversible deprotonation–protonation process. Enantioenriched 9-substituted 9H-fluorene frameworks were finally constructed through an asymmetric vinylogous Michael addition to nitroolefins, followed by a cascade cyclization and oxidative aromatization process, under the catalysis of a chiral bifunctional thiourea-tertiary

A series of 24 cyclohexylaralkylamine derivativesrelated to perhexiline has been synthesized and screened for cardiovascular activity. All the compounds contained an exocyclic amine which was substituted either by an alkyl, cycloalkyl, or aralkyl group. In the hope of further reducing toxicity, the synthesis of p-tolyl- and p-hydroxyphenyl derivatives 23 and 24 was undertaken. The effect of separating

reagent, a widerange of alkenes can be converted into acid products via a carboxyl group transfer strategy in an additive-free fashion. Mechanistic studies revealed that radical anion species (CO2•– and carbon radical anions derived from the reduction of alkenes) are key intermediates of the transformation. This method has the advantages of high catalytic efficiency and a simplecatalytic system, which
