G. Appendino et al., THE CHEMISTRY AND OCCURRENCE OF TAXANE DERIVATIVES .10. THE PHOTOCHEMISTRY OF TAXINE-B, Gazzetta chimica italiana, 124(1), 1994, pp. 1-4
The photodegradation of taxine B, 1, gave, besides the expected cycliz
ation of the 13-oxo-DELTA4(20),11-taxadiene system, reductive cleavage
of the nitrogen-carbon bond. The same behaviour was found in other Wi
nterstein acid esters, which were photolytically converted to their co
rresponding beta-phenylpropionates.
