ChemInform Abstract
In the presence of the chiral sulfide (V), generated from (+)-10- camphorsulfonyl chloride, phenyl diazomethane reacts with aromatic as well as aliphatic aldehydes yielding oxiranes like (VIII) in good yield with reasonable enantioselectivity. Using its epimer resulting from the thiol (III) lower stereoselectivity is observed.
