NEW CAROTENOID STRUCTURES AND STEREOCHEMISTRY

A review is presented on progress made since the 5th International Symposium on Carotenoids, Madison, USA, 1978, in the following areas: diastereo- and enantio-selectively deuterated carotenes and conformation of substituted ɛ-endgroups, new carotenoids having ɛ-endgroups, carotenes with vic. diolgroups, carotene-5,6- and 5,8-epoxides, structure of Z/E-isomeric carotenes and carotenoids, chirality of selected carotenoids, new findings on carotenoids from rose flowers.
