Reaction Steps

A solution of the allylic alcohol 23-9 (0.402 g, 1.24 mmol) in (EtO)3CMe (20 mL) was treated with 1 uL propionic acid. The yellow solution was heated at reflux until complete by 1 cms. The solution was cooled to room temperature, concentrated, and purified by PCTLC (4 mm, 0–10% MeOH/CHCl3) which provided 0.198 g (37% yield) of 23-10.
