A Direct and Versatile Synthesis of 5-(2-Di-n-Propylaminoethyl)-7-methoxyindole
摘要:
The Pummerer intermediate generated from 10 with TFAA was trapped intermolecularly in the presence of Lewis acid by the indoline 2 at position 5. Sequential treatment of the resulted compound 3 with Ra-Ni, LiAlH4 and active MnO2 gave compound 6 in high overall yield.

Gold-catalyzed C5-alkylation of indolines and sequential oxidative aromatization: access to C5-functionalized indoles

日期:——
novel protocol for the synthesis of C5-alkylated indole derivatives via a gold-catalyzed reaction of indolines with diazo compounds and subsequent oxidative aromatization has been developed. C–H bond functionalization selectively occurs at the C5-position of indolines without a directing group. The experimental operation is simple and the whole process can be manipulated in one-pot.

The invention relates to a compound of formula (I), wherein i.a. A1is -CH2- or -C(O)-; one of R1 and R2 is hydrogen and the other one is -A2 -C(O)-R3; A2 is NH- or absent; and R3 is (A), (B) or (C) The compounds are preferential agonists of the cannabinoid receptor 2 (CB2) and can be used as medicaments for the treatment of pain, inflammation, ischemia, etc.
Axially chiral C–N compounds are an emerging but scarcely investigated class of stereogenic molecules with potential applications as biologically active scaffolds and chiral ligands. The synthesis of these compounds is extremely challenging, and in particular, no metal-catalyzed asymmetric, intermolecular C–N coupling has been previously reported. Herein we disclose an intermolecular atropselective
