sulfides and β-hydroxyl nitriles by ring opening of epoxides with aromatic, aliphatic, and heterocyclic thiols and trimethylsilyl cyanide at room temperature under solvent free conditions. All the reactions proceeded satisfactorily in short times and afforded the corresponding products in good to excellent yields with high regioselectivity and chemoselectivity under mild reaction conditions.

The present invention provides novel substituted alkynyl compounds, pharmaceutical acceptable salts and formulations thereof useful in modulating the protein tyrosine kinase activity, and in modulating cellular activities such as proliferation, differentiation, apoptosis, migration and invasion. The invention also provides pharmaceutically acceptable compositions comprising such compounds and methods of using the compositions in the treatment of hyperproliferative disorders in mammals, especially humans.
A process for preparing 3-pyrrolidinol having the formula (II): ##STR1## or a salt thereof, which comprises reducing 4-chloro-3-hydroxybutyronitrile having the formula (I): ##STR2## to convert said 4-chloro-3-hydroxybutyronitrile (I) into said 3-pyrrolidinol (II). According to the present invention, 3-pyrrolidinol, particularly optically active 3-pyrrolidinol can be prepared economically and efficiently.
