%X The acid- catalysed reaction of aldehydes or ethyl vinyl ether with &#946;- hydroxy acids containing a spiro ring is described. For example, 7,9- dioxadispiro [4.0.5.4]pentadecan-10-one was obtained in 90% yield from the reaction of (6-hydroxyspiro[4.5]dec-6-yl)acetic acid and 1,3,5- trioxan and 8-methyl-7,9-dioxadispiro[4.0.5.4]pentadecan-10-one was obtained in 72% yield from (6-hydroxyspiro[4.5]dec-6-yl)acetic acid and ethyl vinyl ether.
