A FACILE, STEREOSELECTIVE PREPARATION OF (Z)-2,4-PENTADIENOATES BY FAVORSKII REARRANGEMENT
Engler, Thomas A.,Falter, Wolfgang
, p. 4115 - 4118 (2007/10/02)
Reaction of 1,3,4-tribromo-2-alkanones, efficiently prepared by direct bromination of the parent enone, with methanolic sodium methoxide gives methyl (Z)-2,4-pentadienoates with high (Z) selectivity about the α,β-double bond.
