Reaction Steps
Alternatively to §6.2.3., halovinyl derivatives can be obtained by Wittig olefination of the 1-[(1S)-1-(tertbutoxycarbonyl)propyl]-5-oxo-3-pyrrolidinecarboxaldehyde 396 in the presence of a phosphine and an halogenomethane. For example of 2-(2-oxo-4-(2-(Z)-fluorovinyl)-1-pyrrolidinyl)butanoic acid 2,2-(dimethyl)ethyl ester is obtained from aldehyde 396 by successive reaction with CFCl3 and n-Bu3P followed by dephosphorylation of the intermediate vinylic phosphonium by NaOH.
