CuI-catalyzed coupling of gem-dibromovinylanilides and sulfonamides: An efficient method for the synthesis of 2-amidoindoles and indolo[1,2-a] quinazolines

A Cu(I)-catalyzed, intermolecular protocol for the synthesis of 2-amidoindoles and tetrahydroindolo[1,2-a]quinazolines in shorter time and high yields is reported. The key highlight of this disclosure is the formation of 2-amidoindole and tetrahydroindolo[1,2-a]quinazoline moieties directly from gem-dibromovinylanilides and sulfonamides in a one-pot fashion through the in situ formation of ynamides followed by a base-promoted intramolecular hydroamidation.

The synthesis of a combretastatin A-4 based library and discovery of new cooperative ortho-effects in Wittig reactions leading to (Z)-stilbenes

A synthesis of combretastatin A-4 and a small library of analogues led to the discovery of some new cooperative orthoeffects allowing (Z)-stilbenes to be prepared in high yield and diastereomeric ratio. Georg Thieme Verlag Stuttgart.

Cyanocuprate-Mediated Intramolecular Biaryl Couplings Applied to an Ellagitannin. Synthesis of (+)-O-Permethyltellimagrandin II

Generation of an intramolecularly tethered, nonracemic diaryl cuprate followed by its oxidation with ground state oxygen at -78 deg leads to a biaryl precursor to an ellagitannin.Subsequent attachment of the appropriate glucose unit completes the synthesi

A SIMPLIFIED ISOQUINOLINE SYNTHESIS

A simple variation of the Pomeranz-Fritsch cyclization provides a short, efficient route to isoquinolines.Treatment of benzylic halides or mesylates 1 with the sodium anion of N-tosyl aminoacetaldehyde dimethyl acetal (2) followed by acid-catalyzed cyclization provides an effective, two-step preparation of isoquinolines 4.
