The reaction of 2-thiazolylmethylenetriphenylphosphorane (1a) in benzene with various aldehydes gives 2-alkenylthiazoles in variable E/Z ratios. Application of the thiazole-to-formyl deblocking protocol to the mixture of the olefins leads to saturated aldehyde homologues having two more carbon atoms.
