Molecular Conformation of N,N'-Diarylthioureas: an Assessment by 1H NMR and Infrared Spectroscopy

Several N,N'-dipyridyl- and N-phenyl-N'-pyridyl-thioureas were examined in different solvents at various temperatures by 1H NMR in order to study their conformational properties.The influence of concentration and the methyl substituent in the pyridine ring on the chemical shifts of the NH and pyridine groups was investigated.The observed chemical shifts are analysed in terms of the conformational properties of the molecules.Free energy barriers to the internal rotation about the C-N bonds have been determined.Infrared spectra have been measured to supplement the NMR studies.Intramolecular hydrogen bonding played a major role in the preferred conformation of pyridylthioureas.The data further revealed an interesting dynamic exchange phenomenon occuring in symmetric N,N'-dipyridylthioureas between two intramolecularly hydrogen bonded conformers.

Micelle-Enabled One-Pot Guanidine Synthesis in Water Directly from Isothiocyanate using Hypervalent Iodine(III) Reagents under Mild Conditions

In this work, we developed a one-pot synthesis of guanidine directly from isothiocyanate using DIB (diacetoxyiodobenzene) as a desulfurizing agent under micellar conditions in water. Our optimization study revealed that the use of 1 % TPGS-750-M as a surfactant with NaOH as an additive base at room temperature can convert a variety of isothiocyanates and amines into corresponding guanidines in excellent yields (69–95 %). This synthetic process in water can be applied to prepare guanidine at gram-scale quantity. Our aqueous micellar medium also demonstrated high reusability as the reaction can be performed for several cycles without losing its efficiency. The reaction is metal-free, utilizes water as solvent and practical (room temperature and open flask).

Fused polycyclic nitrogen-containing heterocycles : 1117. 4-Hydroxy-3-phenyl-2-(2-pyridylimino)-and 4-hydroxy-2-phenyl-3-(2-pyridyl) thiazolidines and related thiazolo[3,4-a]quinoxalines

The condensation of methyl phenylchloropyruvate with 1-phenyl-3-(2-pyridyl) thiourea and its 3-and 4-picolyl homologs affords the corresponding 4-hydroxythiazolidines, which react with o-phenylenediamine to give one of two possible thiazolo[3,4-a]quinoxalines containing the pyridyl-or picolylimine substituents at position 1. 3a-Hydroxy-3-phenylimino-1-(2-pyridyl)thiazolo[3,4- a]quinoxalin-4-(3H,5H)-one, which is a covalent hydrate of the final product, was isolated as an intermediate in this reaction.
