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.

Compounds of the formula STR1 wherein n is either 0 or 1; R1 and R2 is hydrogen and the other is hydrogen, hydroxy, oxo group, a protected hydroxy or protected oxo group; R3 is hydroxy oxo group, =CH--CH2 --OH, =CH--CHO or one of the foregoing groups where the hydroxy or oxo functions are protected; R4 is --CO--OR6, --CO--R6, --CO--NR6 R7, --CO--Cl or --SO2 --R6 ; R6 is saturated or aromatic hydrocarbon; and R7 is saturated or aromatic hydrocarbon or hydrogen, are converted by cleavage of R4 OH into corresponding cycloalkenes and protecting groups, if present, are hydrolyzed. The compounds obtained are valuable intermediates in carotenoid syntheses.
