A bifunctional squaramide-catalyzed reaction of pyrazolin-5-ones with o-quinone methides in situ generated from 2-(1-tosylalkyl)phenols has been successfully developed, providing a facile access to chiral pyrazolones with high enantioselectivities. In addition, the chiral spiropyrazolones with adjacent tertiary and quaternary stereogenic centers can also be obtained through cascade chlorination/cyclization of the chiral pyrazolones.

A concise synthesis of 2-(2-hydroxyphenyl)acetonitriles has been developed through reaction of trimethylsilyl cyanide and the o-quinone methides in situ generated from 2-(1-tosylalkyl)phenols under basic conditions. In addition, 2-(2-hydroxyphenyl)acetonitriles could be conveniently transformed to benzofuranones.

A novel and efficient method for the generation of o-quinone methide intermediates was developed from the readily available 2-tosylalkylphenols under the mild basic conditions, and their reactions with sulfur ylides were investigated for the stereoselective synthesis of trans-2,3-dihydrobenzofurans.
