A new ring for your indole: An unprecedented copper‐catalyzed enantioselectiveFriedel–Craftsalkylation/N‐hemiacetalization cascade reaction with indoles and β,γ‐unsaturated α‐ketoesters is reported. This mild strategy provides new access to various synthetically and biologically important 2,3‐dihydro‐1H‐pyrrolo[1,2‐a]indoles in a highlyenantioselective manner.
吲哚的新环:据报道,铜与吲哚和β,γ-不饱和α-酮酸酯发生了前所未有的铜催化对映选择性Friedel-Crafts烷基化/ N-半缩醛化级联反应。这种温和的策略以高度对映选择性的方式为各种合成和生物学上重要的2,3-二氢-1 H-吡咯并[1,2- a ]吲哚提供了新途径。

classic SN2 reaction of an amine with an alkyl electrophile, both with respect to reactivity and to enantioselectivity. In this study, we describe the development of a user-friendly method (reaction at room temperature, with commercially available catalyst components) for the enantioconvergent nucleophilic substitution of racemic secondary alkyl halides (α-iodolactams) by indoles. Mechanistic studies are
The invention provides specific small molecule compounds that allosterically regulate the activity or modulate protein-protein interactions of AGC protein kinases and the Aurora family of protein kinases, methods for their production, pharmaceutical compositions comprising same, and their use for preparing medicaments for the treatment and prevention of diseases related to abnormal activities of AGC protein kinases or of protein kinases of the Aurora family.

Caught in transition: An efficient catalytic system is the key to the successful development of the first highly diastereo‐ and enantioselectiveannulation reaction betweenindoles and transientnitrosoalkenes. This robust reaction affords structurally unique architectures with up to three new chiral centers. The products can be readily elaborated into other indoline‐based chiral heterocyclic motifs
