substitution pattern at C(5), with aryldiazonium salts 1 either at their C(3) or C(5) position yielding the corresponding 3-arylazo-2-morpholinothiophenes 9 or, under elimination of the substituent at C(5), 5-arylazo-2-morpholinothiophenes 10. This reaction contrasts to the behaviour of 5-morpholinothiazoles 8 and dimethylaniline 13 towards the same diazonium salts 1 which are unable to couple with these compounds

The Vilsmeier reaction of N-substituted 2-arylamino-thiophenes-5-carboxylic acid or their alkyl derivatives gives rise, depending on the substitution pattern at the thiophene moiety, to the formation of either N-substituted 2-arylamino-thiophene-5-carbaldehydes, corresponding imminium salt precursors, or novel thieno[2,3-b]quinoliniumsalts. These salts are highly reactive towards nucleophiles and

Interleukin-2 inducible T-cell kinase (ITK) is a member of the Tec kinase family and is involved with T-cell activation and proliferation. Due to its critical role in acting as a modulator of T-cells, ITK inhibitors could provide a novel route to anti-inflammatory therapy. This work describes the discovery of ITK inhibitors through structure-based design where high-resolution crystal structural information was used to optimize interactions within the kinase specificity pocket of the enzyme to improve both potency and selectivity.

We have previously attempted to prepare5-(4-morpholinyl)-2-aminothiophene (3) by reducing 5-(4-morpholinyl)-2-nitrothiophene (2), to prepare a precursor for the preparation of thienyloxazolidinones as potential linezolid-like antibiotics. This strategy failed, but allowed us to define an interesting reductive aromatization reaction. We have now succeeded in producing thienyloxazolidinones using an
