Abstract (en)
[origin: FR2849025A1] Difluoromethylene-substituted allyl esters (I) are new. Difluoromethylene-substituted allyl esters of formula (I) are new. Rf = a radical comprising a perfluoromethylene group; R1, R3 = H, alkyl or aryl; and Y' = an electroattractive group, such that Y'-O-H is an acid having a pKa of no more than 8(more preferably 5). Independent claims are also included for the following: (1) the preparation of (I); and (2) use of (I) as a precursor for the preparation of heterocyclic compounds substituted by an Rf group, by cyclocondensation with a co-substrate with two double bonds.
