identification and synthesis of macrolide pheromones of the grain beetle oryzaephilus surinamensis and the frog spinomantis aglavei.	macrolide lactones, the so called cucujolides derived from unsaturated fatty acids, are aggregation pheromones of cucujid grain beetles. thirty years ago, oehlschlarger et al. showed that (3z,6z)-dodeca-3,6-dien-11-olide (4) and the respective 12-olide (7) attract the sawtoothed grain beetle oryzaephilus surinamensis, whereas (5z,8z,13r)-tetradeca-5,8-dien-13-olide (5) increases the response synergistically. the frass of this beetle is attractive for its parasitoid cephalonomia tarsalis, which p ...	2014	24523150
identification, synthesis and mass spectrometry of a macrolide from the african reed frog hyperolius cinnamomeoventris.	the contents of the gular glands of the male african reed frog hyperolius cinnamomeoventris consist of a mixture of aliphatic macrolides and sesquiterpenes. while the known macrolide gephyromantolide a was readily identified, the structure of another major component was suggested to be a tetradecen-13-olide. the synthesis of the two candidate compounds (z)-5- and (z)-9-tetradecen-13-olide revealed the former to be the naturally occurring compound. the synthesis used ring-closing metathesis as ke ...	2016	28144343
