Abstract
A one-pot procedure was developed for the synthesis of 3-chloro-3-arylpropanols, which
are important starting materials for the synthesis of biologically active benzanilide
derivatives. Styrenes were reacted with methylene diacetate in the presence of boron
trifluoride to give the corresponding 3-chloro-3-arylpropanols in 36-84% yield by
the Prins reaction. A strongly electron-donating methoxy substituent at either the
ortho or para position of the styrene did not give the expected 3-chloro-3-arylpropanols due to
polymerization. Styrene with a strongly electron-withdrawing nitro substituent gave
the corresponding 3-chloro-3-arylpropanol in very low yield. Under the same reaction
conditions, substituted norbornene gave a tricyclic ether. A very easy procedure for
the synthesis of methylene diacetate is also reported.
Key words
Prins reactions - ethers - Lewis acids - arylpropanols
