    摘要: The compounds of the invention are characterised by the formulae ##STR1## wherein index p represents an integer equal to 2 or 3 and q can take the value zero or 1, with the provision that p+q=3. Said compounds are obtained from hex-3-yne-2,5-diol following a process which comprises reacting an ethylenic compound of formula(CH.sub.3).sub.2 C.dbd.C(H).sub.n (CH.sub.3).sub.m (I)wherein index n represents an integer equal to 1 or 2 and m can take the values zero or 1 and wherein n+m=2, with hex-3-yne-2,5-diol, followed by the oxidation of the acetylenic ether obtained by means of ruthenium tetroxide. The compounds of formula (III) can be used as intermediate products for the preparation of 4-hydroxy-2,5-dimethyl-3(2H)-furanone (Furaneol.RTM.).
