Delving into the Latest Updates on Chinoin Zrt. with Synapse

Overview

A new Pd/MgLa mixed oxide and the known Pd/MgAl hydrotalcite catalysts were applied and recycled successfully in catalytic transfer hydrogenation reactions in ionic liquidsSome α,β-unsaturated carboxylic acid derivatives were hydrogenated in excellent yields.The catalysts were recycled without significant loss of activity.Besides that, a number of halogenated aromatic compounds were dehalogenated under similar catalytic transfer conditions.

The formation of enamino aldehydes and acrylamides from tertiary propargylamine N-oxides in protic media can be interpreted as a novel prototropic rearrangement.The proposed rearrangement mechanism is supported by isotopic labeling experiments and by relevant literature data.

AbstractA facile convergent total synthesis of the selective, potent, and orally active V2 non-peptide antagonist, SR-121463, was developed by modification of the discovery route. One of the late intermediates, the sulfonyl chloride 1, was synthesized from 3-hydroxybenzoic acid (19) by regioselective sulfonation, O-methylation and amidation in four steps. Another late intermediate, indolin-2-one 2, was prepared from p-phenetidine (8) through the indolin-2-one 16, where the cyclohexanone moiety of 27 was introduced into the active 3-methylene group of 16 by sequential transformation using methyl acrylate and KOtBu. After formation of the cyclic ketal moiety of 13, its ring-opening was achieved by using NaBH4 in the presence of CCl3COOH. The morpholino group in 2 was introduced in accordance with the discovery approach, starting from the 2-hydroxyethoxy derivative 14 through the tosyloxy derivative 15 with morpholine in a one-pot reaction. In this way, the indolin-2-one 2 was synthesized from 8 in six steps. Finally, acylation of the indolin-2-one 2 was achieved with the sulfonyl chloride 1 in the presence of KOtBu in dimethyl sulfoxide (DMSO) at room temperature. This synthetic route proved to be applicable for the large-scale synthesis of SR-121463.
