Water-Tolerant ortho-Acylation of Phenols

A metal-free, water-tolerant, and one-pot process for ortho-acylation of phenols promoted by the iodine source/hydrogen peroxide system has been developed. This transformation undergoes ether formation, iodocyclization, C-C bond cleavage, and oxidative hydrolysis in a one-step manner, which is supported by control experiments.

Direct Preparation of 3-Iodochromenes from 3-Aryl- and 3-Alkyl-2-propyn-1-ols with Diaryliodonium Salts and NIS

On the basis of a study of the O-phenylation of 3-phenyl-2-propyn-1-ol with diphenyliodonium triflate and t-BuONa, a variety of 4-aryl-3-iodo-2H-benzopyrans were prepared in good to moderate yields in one pot from the reaction of 3-aryl-2-propyn-1-ols wit

Synthesis of 3,4-disubstituted 2H-benzopyrans through C-C bond formation via electrophilic cyclization

(Chemical Equation Presented) The electrophilic cyclization of substituted propargylic aryl ethers by I2, ICl, and PhSeBr produces 3,4-disubstituted 2H-benzopyrans in excellent yields. This methodology results in vinylic halides or selenides un

Intramolecular iodoarylation reaction of alkynes: Easy access to derivatives of benzofused heterocycles

The iodoarylation reaction of heteroatom-tethered ω-aryl-alkynes offers an efficient and straightforward entry to heterocycles. As a result, both C-C ring-closing from readily available precursors, and concomitant selective iodination take place. The firs
