A chiral SPINOL derived phosphoric acid-catalyzed asymmetric N-alkylation reaction of indoles with cyclic -diaryl-substituted N-acyl imines, which are generated in situ from 3-aryl 3-hydroxyisoindolinones, has been demonstrated. The transformation proceeds smoothly with a broad range of indoles and isoindolinone alcohols. A variety of indole derived N-alkylated tetrasubstituted chiral aminals were afforded in moderate to good yields (50-79%) with excellent enantioselectivities (up to 98% ee).

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 59-87-0, in my other articles.

For the purpose of separating nitrogen compounds, pyrrole and indole, N-methylformamide (NMF) was selected as the extractive solvent. The liquid-liquid equilibrium (LLE) data for {NMF + pyrrole/indole + alkanes} systems were measured at 298.15 K under atmospheric pressure of 101.3 kPa. The triangular diagrams of the above eight systems, {NMF + pyrrole/indole + n-hexane/n-heptane/n-decane/n-dodecane}, were classified as Treybals type I. Meanwhile, the nonrandom two-liquid (NRTL) and universal quasi-chemical (UNIQUAC) activity coefficient models were applied to correlate the LLE data, and the UNIQUAC model shows better agreement than the NRTL model. In addition, the distribution constant and selectivity factor were calculated on the basis of the experimental data and utilized to investigate the extraction capabilities of NMF for pyrrole and indole.

Oxidative [3+3] cycloadditions offer an efficient route for six-membered-ring formation. This approach has been realized based on an electrochemical oxidative coupling of indoles/enamines with active methylene compounds followed by tandem 6 pi-electrocyclization leading to the synthesis of dihydropyrano[4,3-b]indoles and 2,3-dihydrofurans. The radical-radical cross-coupling of the radical species generated by anodic oxidation combined with the cathodic generation of the base from O-2 allows for mild reaction conditions for the synthesis of structurally complex heterocycles.

The first synthesis of raputimonoindole A from the tree Raputia praetermissa (Rutaceae) is reported, starting from indole-5-carbaldehyde. The key step is Braun ‘ s diastereoselective Heck-Suzuki cascade that assembled the prenylated methylenetetrahydrofuran moiety. The unsubstituted indole enamine functionality was tolerated, and the absolute configuration of naturally occurring raputimonoindole A is assigned as (R,R). Raputimonoindole B was accessed by Ir-catalyzed C-H activation/borylation followed by Suzuki-Miyaura cross-coupling. Two biosynthetically related 5-(dihydrofuran-2-yl)indole derivatives from R. simulans were synthesized by ring-closing metathesis, and their absolute configurations were determined.
