Abstract:

Chiral mono- and bis-(thio)urea supramolecular organocatalysts were studied in the enantioselective vinylogous addition reaction of 2-trimethylsilyloxyfuran (TMSOF) to carbonylic compounds; the corresponding chiral γ-hydroxymethyl-butenolides are obtained in good yields and with high enantiomeric excesses. The catalyst structure, as well as the reaction conditions, strongly influence the efficiency of the reaction. The conformational features of mono(thio)urea catalysts 2 and 3 and bis(thio)urea catalysts 7 and 8 were investigated by DFT calculations along with the structure of their complexes

Abstract:

This author's brief review covers works for the period 2013 ‒ 2019, which reflects publications on the synthesis of new electrophilic reagents based on 1,3-bis(dimethylaminomethyl)(thio)urea obtained by the reaction of (thio)urea with bis(dimethylamino)methane. Subsequent transformations of 1,3-bis(dimethylaminomethyl)(thio)urea in catalytic amino- and thiomethylation with N,S-nucleophiles make it possible to obtain nitrogen and sulfur-containing saturated heterocyclic and acyclic compounds.Amines, amides and hydrazides of carboxylic acids, as well as α,ω-dithiols act as N- and S-nucleophiles.

Abstract:

The synthesis of novel chiral (thio)ureas 1–10 and 14–26 is described. These (thio)ureas incorporate chiral auxiliaries derived from (R)- or (S)-α-phenylethylamine, (R)-phenylglycine, or (1R,2S)-ephedrine. The phenylethyl group in compounds 1–10 and 21–24 adopts a particular orientation in the molecular structure as a consequence of 1,3-allylic strain with the (thio)carbonyl group. Ureas 1–10 were tested as Lewis basic organocatalysts in epoxide ring opening and in aldolic condensation, and it was found that the tetrasubstituted urea (R,R)-2 afforded the best results in terms of reaction yield

Abstract:

Novel substituted s-triazine based derivatives were prepared by condensation of 2,4,6-trichloro-1,3,5-s-triazine with anisole, p-trifluoromethyl aniline and amino acid chloride, upon which the compounds were derivatized to their phenyl(thio)urea derivatives, and evaluated for their antiviral activity against human immunodefiency virus HIV-1 (IIIB) and HIV-2 (ROD). The structures of novel synthesized compounds have been established on the basis of 1H NMR, FTIR spectral data and elemental analysis.

Abstract:

Oepen and Vögtle in 1979 recorded the formation of a number of ‘neutral molecule complexes’ between urea (ur) and/or thiourea (tu) and a number of N,N′-aromatic chelate bases derivative of 2,2′-bipyridine (bpy), motifs now widely utilized in essays in studies of molecular/crystal architecture. The structures are recorded of a number of their adducts, namely (a) bpy/ur (1 : 1), (b) phen/ur (1 : 1), (c) phen/tu (1 : 1), (d) dmp/ur (1 : 1), together with (e) bpy/tu (1 : 1) and (f) a dmp/tu adduct of 1 : 2 stoichiometry (phen = 1,10-phenanthroline; dmp = 2,9-dimethyl-1,10-phenanthroline).

Abstract:

Ureidocavitand 1 and thioureidocavitand 2 bind in CH3CN organic anions such as acetate, propionate, butyrate, etc. with K values of 2-8 × 105 l mol-1 and 2-9 × 106 l mol-1, respectively, as was determined with isothermal microcalorimetry (ITC). Bringing together four (thio)urea binding sites on a molecular platform gives rise to about 2000 times higher binding constants, compared with those of the corresponding single binding sites. Glucose- and galactose-containing thioureidocavitands 5 and 6 bind acetate in 1:1 CH3CN/water with a K-value of 2.15 × 103 l mol-1.

Abstract:

A series of substituted thiazine bearing bis-imine derivatives were synthesized by the following three steps. In a first step substituted acetophenones were condensed with terephthaldehyde through clasien-schmidt condensation reaction yielded as substituted bis-chalcones. In a second step substituted bis-chalcones were condensed with thio-urea with sodium hydroxide as base. In a third step have been achieved by condensation between second stage compounds of substituted bis-thaizine with benzaldehyde in presence of catalytic amount of acetic acid. All steps of the reactions were achieved throug

Abstract:

A series of 24 derivatives of tetrahydroquinazolinone has been synthesized by one-pot cyclocondensation reaction of N-allyl quinolones, cyclic ?-diketones and (thio)urea/N-phenylthiourea in presence of lanthanum triflate catalyst. This methodology allowed us to achieve the products in excellent yield by stirring at room temperature. All the synthesized compounds were investigated against a representative panel of pathogenic strains using broth microdilution MIC (minimum inhibitory concentration) method for their in vitro antimicrobial activity.

Abstract:

The quorum sensing (QS) system in multi-drug-resistant bacteria such as P. aeruginosa is primarily responsible for the development of antibiotic resistance and is considered an attractive target for antimicrobial drug discovery. In this study, we synthesised a series of novel selenourea and thiourea-containing dihydropyrrol-2-one (DHP) analogues as LasR antagonists. The selenium DHP derivatives displayed significantly better quorum-sensing inhibition (QSI) activities than the corresponding sulphur analogues. The most potent analogue 3e efficiently inhibited the las QS system by 81% at 125 µM a

Abstract:

Organocatalysis, now running its second decade of life, is being considered one of the main tools a synthetic chemist has to perform asymmetric catalysis. In this review the synthesis of six-membered rings, that contain multiple chiral centers, either by a ring closing process or by a functionalization reaction on an already existing six-membered ring, utilizing bifunctional (thio)ureas will be summarized. Initially, the use of primary amine-thioureas as organocatalysts for the above transformation is being discussed, followed by the examples employing secondary amine-thioureas. Finally, the u
