Pd-Catalyzed Nucleophilic Allylic Alkylation of Aliphatic Aldehydes by the Use
Allyl Alcohols. — Under catalysis of Pd(OAc) 2/PBu3, diethylzinc enables various
31- 056 of
allylic alcohols to undergo nucleophilic allylation of aliphatic aldehydes and ketones.
The reaction is irreversible and kinetically controlled. Unique regio- and stereoselectivites are observed in the case of unsymmetrically substituted allylic alcohols. Cyclic
hemiacetals react also under the present conditions (to be continued). — (KIMURA,
