2-cyclopropylidene-phenoxy ethanes 5, 2-substituted with alkyl, aryl or heterocyclic groups are readily obtained in high yields by the Wittig reaction of the easily accessible α-phenoxy etanones 4 with (3-bromo propyl) triphenylphosphonium bromide. They react with complete regioselectivity in palladium (0) catalyzed nucleophilic substitutions with a series of soft carbon nucleophiles giving an easy entry to 5,6-methanoamino acids.
