Versuchsvorschrift

The neat allyl ether 22-2 from Step A (7.0 g, 38.6 mmol) was heated in an oil bath at 230 ° C. for 1 h. The reaction was followed by NMR and was found to be complete after 90 min. The resulting brown oil was cooled and subjected to column chromatography (1:1 EtOAc/Hexane) to afford 22-3 as a white solid.
