Regioselective alkylation and olefination of allylic carbanion stabilized by two different heteroatoms: Phosphorus and silicon

Treatment of allylphosphonate with LiHMDS, followed by successive addition of chlorotrimethylsilane and carbonyl reagent, afforded dienylsilanes in good yields. 3-Substituted dienylsilanes were obtained by alkylation and olefination of allylic carbanion of 3-trimethylsilylallylphosphonates.

Novel One-pot Synthesis of 1-Iodo-1-trimethylsilyl 1,3-Dienes

Iodine was added to 3-(trimethylsilyl)allylic phosphonium ylide regiospecifically to give 3-iodo-3-trimethylsilyl allylic phosphonium ylide, which reacted with carbonyl compounds to give 1-iodo-1-trimethylsilyl 1,3-dienes with high stereoselectivity in good yield.

A Regiochemical Control in the ?-Allylpalladium Substitution. Preparation of Optically Active γ-Silylallylamines

Optically active γ-trimethylsilylallylamine derivatives were prepared from γ-trimethylsilylallyl alcohols via i. derivatization to carbonates and ii. palladium-catalyzed, regioselective allylic substitution by nitrogen nucleophiles without loss of the ena

Reactions of 1,3-bis(trimethylsilyl)propene with carbonyl compounds in the presence of fluoride ions as catalysts, produce selectively (E)-1-trimethylsilylbut-1-en-4-ol. 1,3-Bis(trimethylsilyl)propenyllithium reacts with carbonyl compounds, under formatio

Silylalkenes and -dienes via (Silylalkylidene)phosphoranes

The reaction of the (silylalkylidene)phosphoranes 3 and 4 with the ketones 5 - 7 and 16 leads to the silylated olefins 8 - 10 and 17, 18.With fluorenone (11), 3 affords the spiro compound 14, via (silylpropylidene)fluorene 13, which is also obtained by dehydration of 9--9-fluorenol (12).With the ketones 5 - 7 and 11, triphenylphosphorane (20) yields the silylated dienes 21 - 24.From cyclohexane (22) and tetracyanoethene (25) the spiran 26 is formed by cycloaddition.
