Random copolymers of ?-caprolactone with O-benzyl-protected 4-hydroxy- or 2,4-dihydroxy-δ-valerolactone after hydrogenation form γ-hydroxy functionalized polyesters that degrade via the cyclization to γ-butyrolactone fragments without carboxylic acid formation.

A stereoselective cyclization of an allylic ester to 2,5-disubstituted tetrahydrofurans catalyzed by palladium(0) is demonstrated. In this cyclization, acetoxy heptenol (6a) having a free hydroxy group prefered trans isomer to cis isomer. By the use of the protected acetoxy heptenol (6b), the cis selectivity was observed. The stereoselectivity was enhanced by the use of DPPIO ligand.
