A palladium (Pd)-catalyzed endo-selective Heck reaction of iodomethylsilyl ethers of phenols and aliphatic alkenols has been developed. Mechanistic studies reveal that this silyl methyl Heck reaction operates via a hybrid Pd-radical process and that the silicon atom is crucial for the observed endo selectivity. The obtained allylic silyloxycycles were further oxidized into (Z)-alkenyldiols.

Based on the known coumarin-based prodrug system, a new meptazinol (Z)-3-[2-(propionyloxy) phenyl]-2-propenoic ester (3) was designed and synthesized as prodrug to minimize the first-pass effect of meptazinol (1) and improve the oral bioavailability. The

By using model amines, several amides of coumarinic acid with the phenolic hydroxyl group protected as an ester were prepared. These model amides underwent a facile (t( 1/2 ) 1.5-31 min) lactonization to release the original amine compounds upon esterase catalyzed hydrolysis of the phenolic ester. Such a system can be used for the preparation of esterase-sensitive prodrugs of amine-containing compounds or peptids.
