PILLAR[6]ARENES -- SOLVENT-FREE PROCEDURE
Аннотация: An efficient solvent-​free procedure for the synthesis of pillar[6]arenes has been developed. The procedure involves the solid-​state condensation of finely milled 1,​4-​dialkoxybenzene and paraformaldehyde by grinding in the presence of a catalytic amt. of H2SO4. The use of org. solvents for the extn. of products has also been avoided. Operational simplicity, compatibility with various 1,​4-​dialkoxybenzenes, non-​chromatog. purifn. technique, high yields and mild reaction conditions are the notable advantages of this procedure. A large scale reaction demonstrated the practical applicability of this methodol.

NITROGEN HETEROCYCLES -- FLUORINE -- OXYGEN HETEROCYCLES
Аннотация: New synthetic routes to trifluoromethylated N-heterocycles based on condensations of 2-methoxy-2-methyl-5-(trifluoromethyl)furan-3(2H)-one with bifunctional N-nucleophiles are described. For the first time, trifluoromethyl-containing pyrazoles, pyrazolines and isoxazolines bearing hydrazone or oxime groups could be obtained by a one-pot strategy based on reactions of 5-(trifluoromethyl)furan-3(2H)-one with two equivalents of the corresponding hydrazines or hydroxylamine in the presence of an acid. The interaction of furan-3(2H)-one with ureas proceeded under mild conditions to furnish 1H-furo[2,3-d]imidazol-2(3H)-one derivatives in good yield. Further, a trifluoromethyl-containing quinoxaline derivative was obtained by condensation of furan-3(2H)-one with ortho-phenylenediamine.

ALDOL-CROTONIC CONDENSATION -- LAWESSON'S REAGENT -- ISATIN
Аннотация: A short and robust approach for the synthesis of 2-(hetero)aryl substituted thieno[2,3-b]indoles from easily available 1-alkylisatins and acetylated (hetero)arenes has been advanced. The two-step procedure includes the "aldol-crotonic" type of condensation of the starting materials, followed by treatment of the intermediate 3-(2-oxo-2-(hetero)arylethylidene) indolin-2-ones with Lawesson's reagent. The latter process involves two sequential reactions, namely reduction of the C=C ethylidene double bond of the intermediate indolin-2-ones followed by the Paal-Knorr cyclization, thus affording tricyclic thieno[2,3-b]indoles.

INDOLO[3,2-B]CARBAZOLE -- INDOLE -- THIOPHENE
Аннотация: Novel 5,11-dialkyl-6,12-di(thiophen-2-yl) substituted 5,11-dihydroindolo[3,2-b]carbazoles have been obtained and plausible ways for their further modifications via the Friedel–Crafts reaction are presented. The formylation of these indolo[3,2-b]carbazoles with dichloromethyl alkyl esters catalysed by Lewis acids leads to the formation of the corresponding 2,8-diformyl derivatives. Applicability of this formylation method for modification of indolo[3,2-b]carbazoles bearing electron-rich aromatic substituents at C-6 and C-12 has also been demonstrated. The Knoevenagel condensation of 2,8-dialdehydes with active methylene nitriles has been studied. The measurements of optical and redox properties for a number of new indolo[3,2-b]carbazoles have been performed

Аннотация: Azaheterocyclic derivatives of 1,2-dicarba- closo -dodeca borane (ortho -carborane) are known to be of particular interest due to numerous plausible applications, particularly, in medicine, materials science, and advanced technologies. Three principal synthetic strategies resulting in azaheterocyclic carboranes, in which boron-enriched and azaheterocyclic fragments are linked to each other, either directly by means of the C-C bonds or through a short spacer (CH 2, CH 2 S, CH 2 O, etc.), have been outlined. These synthetic approaches are of general character and can be used both individually and in combination to afford promising organoboron clusters of diverse architectures. 1 Introduction 2 C-C Cross-Coupling Strategies in the Synthesis of Azahetero cyclic Carboranes 3 Carboryne-Based Transformation Strategies 4 Condensation Strategies: Reactions of Decaborane B 10 H 14 with Substituted Acetylenes 5 Conclusion and Outlook.

Аннотация: An efficient procedure for the synthesis of pillar[6]arenes has been developed. The procedure involves the condensation of 1,4-dialkoxybenzenes and paraformaldehyde in the presence of a catalytic amount of H2SO4 or BF3 center dot OEt2 in polar solvent media (acetonitrile, ethyl alcohol, acetone etc.). In all cases the interaction afforded pillar[6]arenes in high yields.
