  Substituent Effects on the Lifetimes and Reactivities of Arylnitrenium Ions Studied by Laser Flash Photolysis and Photothermal Beam Deflection

  摘要：

  Photolysis of 5-substituted-N-tert-butyl-3-methylanthranilium produces transient N-tert-butyl-(2-acetyl-4-substituted) phenylnitrenium ions. This is confirmed by identification of the stable products, transient absorption experiments, and photothermal beam deflection experiments. Analysis of the stable photoproducts shows that the major decay pathway for these species is addition of nucleophiles to the aromatic ring. The kinetics of the these reactions were examined with the goal of determining how various ring substituents affect arylnitrenium ion stability. Rate constants measured for the 4-phenyl and 4-methoxy derivatives are compared with those from previous work. It is shown that a 4-phenyl group stabilizes the nitrenium ion to approximately the same extent as a 4-methoxy group. Both of these substituents stabilize the arylnitrenium ions considerably more than 4-halogens or a 4-methyl group. Time resolved photothermal beam deflection experiments were applied to the 4-cyano and 4-unsubstituted derivatives, which gave no transient absorption spectra. The latter two compounds are shown to have lifetimes of less than 100 ns.

  A one-pot efficient synthetic approach for the rapid construction of spirocyclopenta[a]indene derivatives has been developed via an iodine-initiated cascade ring expansion and intramolecular Friedel-Crafts-type cyclization from propargyl alcohol-tethered alkylidenecyclobutanes under mild conditions with broad substrate scope. This cascade process can be elegantly conducted on a gram scale. A plausible

  We describe herein a silver-catalyzed conversion of 1-(2-aminophenyl)-propargyl alcohols to 4-substituted 3-tosylaminoquinolines using TsN3 as an amino surrogate. Controlled reactions reveal the pathway consisting of Ag(I)-catalyzed 5-exo-dig cyclization, catalyst-free (2 + 3) cycloaddition, and ring-expansive rearrangement via nitrogen expulsion. As a support study, we show that the cyclic enamines

  A sequence of two titanium(III)‐catalyzed reductive umpolung reactions is reported that allows the rapid construction of benzazo‐ and benzoxozine building blocks. The first step is a reductive cross‐coupling of quinolones or chromones with Michael acceptors. This reaction proceeds with complete syn‐selectivity for the quinolone functionalization while the anti‐diastereomers are obtained as the major
