Direct Transformation of Ethylarenes into Primary Aromatic Amides with N -Bromosuccinimide and I2-Aqueous NH3

A variety of ethylarenes were converted into the corresponding primary aromatic amides in good yields via treatment with N-bromosuccinimide in the presence of a catalytic amount of 2,2′-azobis(isobutyronitrile) in a mixture of ethyl acetate and water, acetonitrile and water, or chloroform and water, followed by reaction with molecular iodine and aq NH3 in one pot. It was found that aryl α-bromomethyl ketones and/or aryl methyl ketones were formed at the first reaction step and their iodoform-type reaction occurred at the second reaction step to provide primary aromatic amides. The present reaction is a useful and practical transition-metal-free method for the preparation of primary aromatic amides from ethylarenes. (Chemical Equation Presented).

Chromatography-Free and Eco-Friendly Synthesis of Aryl Tosylates and Mesylates

Two chromatography-free and eco-friendly protocols have been developed to synthesize aryl tosylates and mesylates by the tosylation and mesylation of the corresponding hydroxyarenes, respectively. These protocols are superior to other known ones regarding

An efficient synthesis of lamellarin alkaloids: Synthesis of lamellarin G trimethyl ether

A general and efficient synthesis of lamellarin alkaloids is described. The synthesis involves the formation of the core pyrrolo[2,1-a]isoquinoline, followed by the formation of the lactone ring.
