Silyl enol ethers (2) react with trihutyl [(phenylthio) chloromethyl] stannane (1) in the presence of Zinc bromide to give B-phenylthiomethylstannyl ketones (3) in good yields. Silyl dienol ethers (4) mainly give products (5) due to y-attack, under these conditions. S-Stannyl Carbonyl compounds have
## Site-specific ureidoalkylation of silyl enol ethers can be achieved by their Sumnary: reactions with chloromethylcarbamates at -78' under the influence of titanium tetrachloride.
While regiochemical aspects of enolate chemistry have been studied extensively, 1 virtually no attention has been paid until recently to geometry of the double bond of enolate anions.
