Hydantoins and thiohydantoins derived from 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid

, 2006
The reaction of methyl (S)-1,2,3,4-tetrahydroisoquinoline-3-carboxylate with isocyanates (phenyl, naphthalen-1-yl, cyclohexyl, (S)-1-methylbenzyl) in ether has been used to prepare N-substituted methyl (3S)-2-aminocarbonyl-1,2,3,4-tetrahydroisoquinoline ...

Palladium-Catalyzed Arylation of Hydantoins with Aryl Chlorides Enabled by Ylide-Functionalized Phosphines (YPhos)

The hydantoin moiety is an important structural motif present in various pharmaceuticals. Palladium complexes bearing electron-rich, bulky ylide-functionalized phosphine (YPhos) ligands were found to catalyze the arylation of N-protected hydantoins with ...

Copper-Mediated N-Arylations of Hydantoins

, 2018
A set of two efficient and broadly applicable procedures for the N-arylation of hydantoins at the two nitrogen atoms is reported. The first one relies on the use of stoichiometric amounts of copper(I) oxide under ligandless and base-free conditions and ...

New polyamides based on 1,3-bis(4-carboxy phenoxy) propane and hydantoin derivatives: synthesis and properties

Bulletin of the Chemical Society of Ethiopia, 2010
Six new polyamides 5a-f containing flexible trimethylene segments in the main chain were synthesized through the direct polycondensation reaction of 1,3-bis(4-carboxy phenoxy) propane 3 with six derivatives of hydantoins 5a-f in a medium consisting of N ...
