Abstract The novel acid-catalysed reaction of isopropenyl ether with tertiary acetylenic carbinols to give β-ketoallenes in high yields is described. Upon treatment with bases, these allenes readily undergo isomerization to conjugated dienones. This reaction sequence results in an economic synthesis of pseudo-ionones and pseudo-irones from dehydrolinalool and its homologs.
