Palladium-Catalyzed Alkylation of Vinyl Oxiranes with Substituted Allenes.
Access to Bifunctionalized Allylic Alcohols. — The first regioselective palla44- 096 Direct
dium-catalyzed ring opening—alkylation reaction between vinyloxiranes and substituted allenes is described to give functionalized allylic alcohols (V)/(VI) and (VIII) in
moderate to good yields as E/Z-mixtures. The reaction tolerates a wide range of substituents at the aryl ring but does only proceed with trisubstituted allenes (III) which
are obtained by a modified procedure. — (NANAYAKKARA, P.; ALPER*, H.; J.
