Regiocontrol and Stereoselectivity in Tungsten-Bipyridine Catalysed Allylic Alkylation
Lehmann, Juerg,Lloyd-Jones, Guy C.
, p. 8863 - 8874 (1995)
Tungsten-bipyridine complexes, generated in situ, catalyse the allylic alkylation of isocinnamyl methyl carbonate by dimethyl sodiomalonate with complete syn-stereoselectivity.When para substituted aryl-allyl methyl carbonates are employed, the regioselectivity correlates with Swain-Lupton parameters.Cross-over experiments demonstrate that the reactions do not proceed via the conventional 0> -> II allyl>+ -> 0 allyl-Nu> catalytic cycle.

A Re2O7catalyzed cycloetherification of monoallylic diols is described. The reaction features short reaction time, mild reaction conditions and exclusive E selectivity. A wide range of monoallylic alcohols with alkyl or aryl substituents on olefin smoothly undergo ring closure to deliver corresponding oxa-heterocycles. The reaction is also operationally simple and not sensitive to air and moisture.

In this study, the lipase-catalyzed kinetic resolution (Novozyme 435) was employed to prepare chiral allylic alcohols and acetates with terminal double bonds in enantiomeric excesses ranging from 94 to >99 %.
