A method is described for the synthesis of new carotenoids by transesterification of ethyl-beta-apo-8'-carotenoate. The rate of transesterification was temperature-dependent with highest yields using primary alcohols. Reaction conditions were found avoiding Z isomerization. The structures of the new products were
