9-Hydroxymegastigma-3,5-dien-7-yne 8a was synthesised and shown to be identical to an intermediate found in the acid-catalysed conversion of 3,5,9-trihydroxymegastigma-6,7-diene 4 to β-damascenone 1, 3-hydroxydamascone 5 and megastigma-5-en-7-yne-3,9-diol 6. When subjected to acid hydrolysis, 8a produced β-damascenone 1, in high yield. Importantly, the hydrolysate was completely free of 3-hydroxydamascone 5.

The acid-catalysed reactions of 6,7-megastigmadiene-3,5,9-triol and the β-D-glucosides of 5-megastigmen-7-yne-3,9-diol and 3-hydroxy-β-damascenone have been studied in relation to the formation of damascenone.The results show that hydrolysis of the allene triol could account for damascenone formation in the juices of grapes and other fruits.
