An iridium-catalyzed highly stereoselective transfer hydrogenation of N-protected 2, 4-
disubstituted-1, 5-benzodiazepines as well as dibenzo [1, 5] oxa/thiazepines is realized in …

Abstract Dibenzo [b, f][1, 4] oxazepine (DBO) derivatives possess an array of
pharmacological activities, and are of growing pharmaceutical interest. Twelve recent …

Alkali metal carbonates (M2CO3) are weak bases and are useful in organic synthesis.
Several recent studies have shown that potassium carbonate (anhydrous or as the …

The regioselective synthesis of 1, 4-disubstituted 1, 2, 3-bistriazoles from a variety of N-
propargyl bis (indolyl) methanes with sodium azide using CuI as the catalyst in …

A direct protocol for the asymmetric synthesis of dibenzoxazepine/thiazepine-fused [2.2. 2]
isoquinuclidines is developed. The reaction proceeds through a proline-catalyzed direct …

Asymmetric alkynylation of seven-membered cyclic imine dibenzo [b, f][1, 4] oxazepines is
successfully achieved by combining chiral phosphoric acid and Ag (I) catalysts. Various …

A sequence of the Ugi four-component reaction (U-4CR) and microwave-assisted
intramolecular Ullmann etherification has been established for efficient generation of a …

In this study, an efficient method was designed to graft poly (ethylene glycol) effectively onto
commercial Dowex resin. The catalytic efficiency of the copolymer obtained as a new solid …

A novel method for the preparation of phenolic compounds through ipso-hydroxylation of the
corresponding widely available arylboronic acid precursors is described. Through …

A simple and selective deallylation of allyl ethers and esters using iodine (10 mol%) in
polyethylene glycol-400 as a green reaction solvent is described. The reaction was …
