a-Stannyl derivatives of methyl ketones could be generated from the corresponding silyl enol ethers via a selective silyl/stannyl exchange and were used to prepare aldol products with almost complete regio-and chemo-selectivity. e-Trialkylstannyl ketones and their tautomeric tin enolates are versati
## Abstract α‐Stannylated allylic carbonates (I) smoothly undergo Pd‐catalyzed amination to give the corresponding stannylated allylic amines (III), which are suitable substrates for Pd‐catalyzed Stille coupling reactions [cf.
Silyl b-enaminones have been synthesized by reductive cleavage of silylisoxazoles. These versatile synthons bearing the silyl group in different positions of the enamino ketonic system are of great interest in the construction of a variety of penta-and hexaheterocycles, which, in general, retain the
Primary TMS or TES ethers, in the presence of secondary TMS or TES ethers, are selectively oxidized to the corresponding aldehydes under Swern conditions. A short synthesis of key intermediates towards various natural products has been achieved.
