An asymmetric intramolecular spiro-amination to high steric hindering α-C–H bond of 1, 3-
dicarbonyl via nitrene transfer using inactive aryl azides has been carried out by developing …

Malaria infections affect almost half of the world's population, with over 200 million cases
reported annually. Cryptolepis sanguinolenta, a plant native to West Africa, has long been …

Herein, we reveal an unprecedented domino annulation of N-benzyl-acrylamides with 1, 3-
dicarbonyls for the assembly of fused tricyclic alkaloid frameworks incorporating a spirocycle …

Herein, we present the electrochemical synthesis of selenylated azaspiro [4.5]
decadienones through domino selenylation/ipso-annulation of N-benzylacrylamides with …

An asymmetric sulfa-Michael/aldol cascade reaction of 2-ylideneoxindoles with 1, 4-dithiane-
2, 5-diol catalyzed by squaramide derived from cinchona was first developed to realize the …

Presented herein is a novel synthesis of C2-spiroindoline derivatives based on the cascade
reaction of 2-aryl-3H-indoles with cyclopropanols. The formation of product involves Rh (III) …
