Oxime-catalyzed formation of functionalized 1,3-oxathiolanes from aryl isothiocyanates and oxiranes
摘要:
An efficient synthesis of N-(5-alkyl-1,3-oxathiolan-2-ylidene)arylamines via a one-pot reaction between arylisothiocyanates and substituted oxiranes in the presence of catalytic amount of pyridine-2-carbaldehyde oxime is described.[GRAPHICS].

An efficient synthesis of 1,3-oxathiolane-2-imin derivatives is described via one-pot reaction between arylisothiocyanats, asymmetrically substituted oxiranes and catalytic amount of methanol. The mild reaction conditions and high yields of the products exhibit the good synthetic advantage of this method. (C) 2011 Faramarz Rostami-Charati.
