Diversity-oriented synthesis of chlorinated arenes by one-pot cyclizations of 4-chloro-1,3-bis(trimethylsilyloxy)buta-1,3-dienes

Wolf, Verena,Adeel, Muhammad,Reim, Stefanie,Villinger, Alexander,Fischer, Christine,Langer, Peter

experimental part, p. 5854 - 5867 (2010/03/04)

A variety of 3-chlorosalicylates were prepared by one-pot cyclizations of the first reported 4-chloro-1,3-bis(trimethylsilyloxy)buta-1,3-dienes with various 1,3-dielectrophiles, These include cyclizations with 3-silyloxy-2-en-1-ones, 3-aryl-3-silyloxy-2-en-1-ones, 1-methoxy-1-en-3-ones, 1,1-bis-(methylthio)-1-en-3-ones, 3-oxo orthoesters, 1,1,3,3- tetraethoxypropanes, 1,1-diacetylcyclopropane, and 3-formylchromones.
