A strategy for one-pot synthesis of isoindoles is described via a catalytic multicomponent dehydrogenative annulation of diarylimines, vinyl ketones and simple amines. In the presence of a rhodium catalyst and Cu oxidant, four C–H and two N–H bonds are activated along with the formation of one new C–C and two new C–N bonds, leading to a series of isoindole derivatives in good to very high isolated

Novel sulfur-containing compounds which inhibit the activity of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase, having a sulfur-containing side-chain bonded to a hydrophobic anchor group through an acetylenic or ethylenic linkage. Pharmaceutical compositions, and methods of use for the treatment or prevention of hypercholesterolemia, atheroschlerosis, hyperlipoproteinaemia and hyperlipidemia are provided, as are novel methods for preparation and intermediate compounds.
N-benzylideneanilines with functionalizedalkenes such as α,β-unsaturated esters gave ortho-substituted benzaldehyde derivatives with a functionalgroup at the remote position after acidic treatment. The present transformation involves deconjugative long-range isomerization (chain-walking) up to 11 times and C–H activation using an imino group as a transient directing group.
在 Ir 催化下,N-亚苄基苯胺与功能化烯烃(如 α,β-不饱和酯)反应得到邻位取代的苯甲醛衍生物,酸处理后在远端位置具有官能团。目前的转化涉及高达 11 次的解共轭远程异构化(链行走)和使用亚氨基作为瞬态导向基团的 C-H 活化。
