A sulfonic acid functionalized tetraphenylethylene-based hypercrosslinked polymer (THP-SO 3H) with a well-developed porous network and accessible sulfonic acid sites was synthesized and characterized by different analytical techniques. The cata

A facile and efficient three-component reaction in the presence of Br?nsted acid in water was developed to synthesize aryl(chalcogen-heteroaryl)methyl sulfones in good to very high yields with broad substrate scope. Our protocol is eco-friendly, metal free, and atom economic. The sulfone products may be efficiently transformed into a bactericidal agent analogue and an aryl heteroaryl ketone.

TEMPO/CuI was found to be an effective catalyst for the cross-coupling of indoles with benzylic amines affording the corresponding bis(indolyl)phenylmethanes under air atmosphere at room temperature in good to excellent yields. The efficiency, easy workup, simplicity, and chemoselectivity of this protocol provide a green and low-cost procedure for the synthesis of these compounds.

, p. 559 - 567 (2015/08/11)
In this paper, N-Boc and N-Cbz protected α-branched amines are synthesized directly from commercially available aromatic/heteroaromatic compounds, aldehydes, and tert-butyl or benzyl carbamate bearing a variety of substituents. Bismuth(III) triflate is found to be a highly effective catalyst for this one-pot, three-component coupling reaction. In addition, the use of mild reaction conditions, low catalytic loading, easy removal of the N-protective group, and one-step synthesis under "open-flask" are advantages of the present procedure.

An efficient synthetic approach to diheteroarylmethanes and 1,3-diheteroarylpropenes has been developed via Yb(iii)-catalyzed sequential self-condensation of 2-furfuryl (or 2-thienyl or 3-indolyl) alcohols followed by intramolecular Friedel-Crafts type re

A variety of symmetrical 1,1-bis(heteroaryl)alkanes are prepared in excellent yields from the reaction of N-(α-benzotriazolylalkyl)carbamate 2 (itself easily available from the condensation of benzotriazole, an aldehyde, and an alkyl carbamate) with an excess of 2-methylthiophene or 2-methylfuran.When methyl N-(α-benzotriazolylalkyl)carbamate 2a is treated with 1 equiv of a heterocycle, the benzotriazolylalkyl-substituted heterocycle is formed.These intermediates react further with other heterocycles to give unsymmetrical 1,1-bis(heteroaryl)alkanes in good yields under mild conditions.
CONVERSION OF DI(FURYL-2)ALKYL AND DI(FURYL-2)ARYLMETHANES TO THE THIOPHENE ANALOGS

, p. 872 - 874 (2007/10/02)
On reaction with hydrogen sulfide in strongly acidic media, difurylalkyl(aryl)methanes are converted to furylthienylalkyl(aryl)- or dithienylalkyl(aryl)methanes, depending on the conditions.
