Product 1

HCID 260493-Carene

Procedure

Δ-3-carene was epoxidized by the above-described procedure, using Di(acetate)3 as catalyst (1% based on the weight of Δ-3-carene) and ethyl acetate as solvent (volume ratio solvent to Δ-3-carene 3:1). The final mol ratio propionaldehyde to Δ-3-carene was 1.5:1, oxygen was bubbled through at a rate of 8 liters/hour, and reaction time was 4 hours.
