Among the ester exchange reaction (Table 1, entries 1 and 2), the decrease of the optical purity of the methyl esters 15 and ent-16 was observed. Namely, the ee value of 15 decreased to 80% from 97% de; at the same time, that of ent-16 dropped down to 51% from 73% de of the original value. This appearance of racemization might be originated form the isomerization between the E- and Z-isomers of the adducts 11-14 and/or methyl esters 15-ent-16 during ester exchange reaction. This consideration has been experimentally supported by the photolysis of the optically pure (Z)-15 with photo-irradiation at 254 nm to give the (E)-16 without any loss of optical purity. See Ref. 10. On the other hand, no isomerization of Z-methyl ester 18 to E-methyl ester 19 occurred at all. See Ref. 17.
