Stepwise bromination of pentaerythritol (34) gives pentaerythrityl tetrabromide (35) in 72% yield (Scheme 14).[34] In the presence of activated zinc (HCl), pentaerythrityl tetrabromide (35) undergoes cyclization to provide methylenecyclobutane (36) in 70% yield. Finally, ozonolysis of methylenecyclobutane (36) gives cyclobutanone (3) in 75% yield (Scheme 14).[34]
