The invention relates to furan derivatives of the formula I, where Y is a group -P(O)A2, where A, simultaneously or each separately, can be halogen, dialkylamino or an alkoxy group; or -C(O)R', where R' can be a tert-alkyl, aryl or hetero aromatic group; or -C(O)OR", where R" can be an alkyl or aryl group, and where Z is hydrogen, halogen, or an alkyl or alkoxy group. The invention also relates to the process for preparing compounds of the formula I. In the process, furanones of the formula II where Z is the same as above, are caused to react with compounds of the formula III where Y is the same as above and L is a group which leaves readily. <IMAGE>
