The Mannich reaction has been used for decades to prepare many pharmaceutically important molecules. Here, using a “double-Mannich−β-elimination” synthetic sequence, we report the synthesis and the characterization details of a novel class of β-amino diaryldienones with prominent antiprostate cancer activity. Through these studies, we correct an erroneous structure in the current literature, present
We show a beneficial new approach to the preparation of 1-methyl-3-phenylisoquinoline derivatives. This method involves heating polyphosphate ester and the appropriate oximes obtained from 3,4-diphenylbut-3-en-2-one derivatives. The isoquinolines were synthesised in yields mainly ranging from about 50 to 70%, and their structures were confirmed by proton and carbon nuclear magnetic resonance spectroscopy
