T riphenylethylene1 and several active derivatives 2–4 have been shown to possess a prolonged œstrogenic activity provided that a dose well above the threshold is administered. Among these ...

Highly enantioselective Friedel–Crafts alkylation of pyrroles with 2-enoyl-pyridine N-oxides in water/chloroform (10:1) was developed under catalysis of Lewis acid. The Friedel–Crafts alkylation ...
