实验过程
Keto-α-isophorone is acetalized. The resulting 7,9,9-trimethyl-1,4-dioxaspiro[4,5]dec-6-en-8-one is condensed with trans-1-hydroxy-3-methyl-pent-2-en-4-yne in the presence of lithium in liquid ammonia and iron-(III) nitrate in ether to give rac. 8-(5-hydroxy-3-methyl-pent-3-en-1-yn-1-yl)-7,9,9-trimethyl-1,4-dioxaspiro[4,5]dec-6-en-8-ol (XVI).
