A Mild and Efficient Synthesis of 3-Aminosubstituted Isothiazole S-Oxides and their 5-Sulfanylsubstituted Derivatives

The present paper describes a mild and efficient method to synthesize 3-aminosubstituted isothiazole sulfoxides taking advantage of arylsulfonyloxaziridines. The reactivity of the resulting isothiazole sulfoxides toward sulfur nucleophiles has been studied and resulted in the formation of 5-sulfanylsubstituted isothiazoles in a fully diastereoselective way. From 3-benzylamino-5-chloro isothiazole S-oxide an addition-elimination reaction took place affording smoothly the corresponding unsaturated 5-sulfanyl derivatives.

A theoretical study of the aromaticity of hypervalent sulfur heterocycles

In this paper we report on the heteroaromaticity of 1,2,5-thiadiazole-1,l-dioxide (I) and its isomers 1,2,4-thiadiazole-1,1-dioxide (II), 1,3,4-thiadiazole-1,I-dioxide (III) and 1,2,3-thiadiazoIe-1,1-dioxide (IV) by calculating their electronic structures and estimating their aromatic character in terms of our previously developed criteria: N, MDQ, Delta E-pi L(NLMO) and Delta E-pi L(Boys) as well as comparing their total energies. (I) is shown to be the most aromatic isomer in good agreement with chemical reasoning and experimental evidence. The 1,l-dioxides of thiazole and isothiazole were predicted to be intermediate in aromaticity between thiophene-l, 1-dioxide and the isomers, (I)-(N). N value measures indicate that thiophene-l,1-dioxide would retain a small measure of aromatic character relative to thiophene (N(thiophene) = 0.868, N(thiophene-l,l-dioxide) = 0.389).

Enantioselective synthesis, chiroptical properties and absolute configuration of 3-aminosubstituted isothiazole S-oxides

Herein we report a mild and efficient method to synthesize chiral 3-aminosubstituted isothiazole sulfoxides taking advantage of (+)- and (-)-((8,8-dichlorocamphoryl)sulfonyl)oxaziridine under microwave irradiation. The determination of the absolute configuration of the chiral sulfoxide was achieved by theoretical calculation of the CD spectra. The reason for the observed stereoselectivity, was enlightened by means of analysis of our data using DFT calculations. (C) 2009 Elsevier Ltd. All rights reserved.

Crystallographic study of two monoazo disperse dyes with a D-pi-A system

Two azo disperse dyes, 2,6-dichoro-4-nitro-4,4-N-cyanoethyl-N-benzyl-azobenzene (D1) and 3-(3-methyl-4-N-ethyl-N-benzyl-phenyldiazenyl)-5-nitro-2,1-benzisothiazole (D2), were synthesised and characterised. The crystal morphologies and single crystal structures were measured. The various packing and supramolecular interactions were described. D1 formed stellate crystals. The two benzene rings bilateral to the azo unit were not coplanar. Their dihedral angle was 75.72 degrees. They were linked by the azo unit and were twisted. The coupling-component N-substituted benzyl and benzene rings were not coplanar. The chemical structure was not the typical azo structure. A dimeric packing mode was formed between adjacent molecules in a head-to-head and tail-to-tail manner. One molecule was inserted between two dimeric molecules in a head-to-tail manner. D2 formed globe crystals. The isothiazole and benzene rings of the azo unit were coplanar, with the typical – conjugated structure. The benzene rings of the azo unit and the coupling-component N-substituted benzyl were vertical. Their torsion angle was 179.9 degrees.
