, p. 45 - 48 (2007/10/02)
The photochemical irradiation of the 2--3-tetrahydropyrones (3) gives the 3-tetrahydropyrone (6) and the δ-valerolactone (7).The structures (S*, R*) or (S*, S*) which were determined by nmr and by comparison with the 2--2-tetrahydropyrannes (5) (S*, R*) and (S*, S*) influence the rate of the photolysis.
