Reaction Steps

Cis-but-2-ene, 4-diol (50 g), cyclohexanone (50 g) and SNCA catalyst (2.5 g) were refluxed in benzene (75 ml) using a Deanstark water separator. The catalyst was filtered, the solvent evaporated and the residue distilled at 80°-85° C./4 torr to give 7,12-dioxaspiro[5,6]dodec-9-ene of formula III (92%) of the drawings.
