A Convenient Preparation of α-(p-Hydroxy- or p-Aminophenyl) Carbonyl Compounds. Addition-Reduction Reaction of Tin(II) Enolate with p-Benzoquinone and Its Mono-N-tosylimino Derivative
Tin(II) enolates react with p-benzoquinone and its mono-N-tosylimino derivative to give 1,2-adducts in good yield.These can be reduced in situ to α-(p-hydroxy- or p-aminophenyl) carbonyl derivatives by addition of dichloromethylsilane and dimethylaminopyr

THE TIN(II) ENOLATE ADDITION REACTIONS TO α,β-UNSATURATED KETONES AND QUINONES
The reaction of tin(II) enolates with various α,β-unsaturated carbonyl compounds is examined.When TMSCl is added as an activator of the α,β-unsaturated ketones, the Michael addition reaction proceeds smoothly to give the corresponding 1,4-adduct in good y
