Chemoselective N–H functionalization of indole derivatives via the Reissert-type reaction catalyzed by a chiral phosphoric acid
Literature Information
Yue Cai, Qing Gu
An asymmetric N-alkylation of indole derivatives via the Reissert-type reaction was realized in the presence of a catalytic amount of chiral phosphoric acid. Various enantioenriched indoles with N-1 substituted by 1,2-dihydroisoquinoline could be obtained under mild conditions in good yields and enantioselectivities at room temperature (up to 98% yield, 94% ee). The current method is compatible with gram-scale reaction and the products can undergo versatile chemical transformations.

Organic & Biomolecular Chemistry

Organic & Biomolecular Chemistry (OBC) publishes original and high impact research and reviews in organic chemistry. We welcome research that shows new or significantly improved protocols or methodologies in total synthesis, synthetic methodology or physical and theoretical organic chemistry as well as research that shows a significant advance in the organic chemistry or molecular design aspects of chemical biology, catalysis, supramolecular and macromolecular chemistry, theoretical chemistry, mechanism-oriented physical organic chemistry, medicinal chemistry or natural products. Articles published in the journal should report new work which makes a highly-significant impact in the field. Routine and incremental work is generally not suitable for publication in the journal. More details about key areas of our scope are below. In all cases authors should include in their article clear rationale for why their research has been carried out.
