groups, such as acetal (for3ae), lactam (for3af), NHBoc (for3ak-ao), OH (for3ah-aj,3ap-ar, and3ba), and ester (3av), were all well tolerated by the reaction. It is especially impressive that for amino alcohols (for3ah-aj,3ap-ar, and3ba) containing one or two much more...
When benzyl chloride was employed, 46% yield of ketone (49) was obtained and a significant amount of by-product ester was formed possibly because of the nucleophilic substitution side reaction. This coupling reaction can allow for the construction of highly functionalized ketones in an operationally...

(21)). Decarboxylative allylations of β-ketoacids with allylic acetates are also possible <86JOC421>. Considerable effort is also being devoted to the development of enantioselective versions of the reaction, although largely withketoesterand malonate nucleophiles. However the palladium(0)-catalysed...

The carbonylative coupling of carvyl phosphates, trans- and cis-1h, and gamma-zincio ester 5 is stereospecific and proceeds with inversion of configuration at the allylic stereocenters to furnish cis- and trans-6h, respectively, as single diastereomers. In the absence of HMPA, the reaction ...
