PHOTOCHEMICAL REARRANGEMENT OF MORTONIN C
Sanchez, A.,Martinez, M.,Rodriguez-Hahn, L.
, p. 1005 - 1008 (2007/10/02)
Irradiation of Mortonin C (1a) produced the photoproducts 4a and 8a as a result of a photochemically induced ring contraction of the tetrahydro-oxepine nucleus.Te structure and stereochemistry of 4a and 8a were proved by chemical degradation and spectrosc
