Patent number: 10150777Abstract: The invention pertains to processes to produce dry biomass of pyripyropene producer organisms, processes to obtain pyripyropenes from such dry biomass, as well as to processes to produce compounds of Formula III and/or Formula IV and/or Formula V from the pyripyropenes obtained from the dry biomass. The invention does further pertain to the dry biomass itself, as well as processes using said dry biomass to obtain pyripyropenes for the production of compounds of Formula III and/or Formula IV and/or Formula V, including processes using said dry biomass to obtain pyripyropenes or compounds of Formula III and/or Formula IV and/or Formula V in order to produce pest control compositions, in particular insecticides, comprising such compounds.Type: GrantFiled: March 3, 2014Date of Patent: December 11, 2018Assignee: BASF SEInventors: Burkhard Ernst, Manfred Ehresmann, Christopher Koradin, Andreas Pletsch, Melanie Bonnekessel, Thomas Kaeding, Karin Schein-Albrecht, Stefanie Demming, Franz Weber, Wolfgang Siegel, Hartwig Schroeder, Stephan Freyer, Peter Oedman
