Pd-catalyzed arylation reactions with phenol diazonium salts: application in the synthesis of diarylheptanoids

J Org Chem. 2011 May 6;76(9):3357-65. doi: 10.1021/jo2002787. Epub 2011 Apr 6.

Abstract

The first total synthesis of the natural product (3S,7R)-5,6-dehydro-de-O-methyl centrolobine and various analogues is reported, using a highly regio- and diastereoselective Mizoroki-Heck reaction of phenol diazonium salts and enantiopure dihydropyrans. The assigned relative configuration was confirmed by single-crystal X-ray structure analysis, but a revision of the absolute configuration is proposed based on polarimetric measurement.
