A catalytic metal-free Ritter reaction to 3-substituted 3-aminooxindoles.
The first Ritter reaction of 3-substituted 3-hydroxyoxindoles with nitriles, catalyzed by HClO(4), is developed, which enables the synthesis of 3-substituted 3-aminooxindoles in good to excellent yield with rich diversity.

The title compound congestiflorone, C(28)H(32)O(4), which was isolated from the stem bark of Mesua congestiflora, consists of a benzophenone skeleton with two attached pyran rings to which a cyclo-hexane ring and a C6 side chain are bonded. The benzene ring is significantly distorted from planarity (r.m.s. deviation = 0.0007 Å) due to the constraints imposed by junctions with the two pyran ring...
متن کاملThe synthesis of 5- picrylamino-1, 2, 3, 4-tetrazole (PAT) from the reaction of 5-amino-1, 2, 3, 4-tetrazole with picryl chloride in different temperature conditions, the DFT method
In this article, synthesis of the explosive synthesis of 5- picrylamino-1, 2, 3, 4-tetrazole (PAT) from the reaction of 5-amino-1, 2, 3, 4-tetrazole with picryl chloride in different conditions of temperature, with density functional theory method were studied. For this purpose, at first the material contained in the both sides of reaction were geometrically optimized, then th...
