Abstract:
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.
Abstract:
La presente invención se refiere a procedimientos para producir biomasa seca de organismos productores de piripiropeno, procedimientos para obtener piripiropenos a partir de esa biomasa seca, así como procedimientos para producir compuestos de la Fórmula III y/o la Fórmula IV y/o Fórmula V a partir de los piripiropenos obtenidos a partir de la biomasa seca. La invención se refiere además a la biomasa seca misma, así como a procedimientos que se valen de dicha biomasa seca a fin de obtener piripiropenos para la producción de compuestos de la Fórmula III y/o la Fórmula IV y/o la fórmula V, inclusive a procedimientos que usan dicha biomasa seca para obtener piripiropenos o compuestos de la Fórmula III y/o la fórmula IV y/o la fórmula V a fin de producir composiciones para control de plagas, en particular insecticidas que contienen esos compuestos.
Abstract:
Un proceso para obtener al menos un piripiropeno, que comprende las etapas de a) cultivar un organismo productor de piripiropeno en un caldo de cultivo en condiciones de cultivo, en el que se produce al menos un piripiropeno, b) producir biomasa seca con un contenido de agua residual (peso/peso) inferior al 8 % de al menos una parte de la biomasa obtenida en la etapa a), c) obtener al menos un piripiropeno a partir de la biomasa seca producida en la etapa b).
Abstract:
The present invention relates to a method for preparing the pyripyropene compound of the formula (I) which method comprises the following steps: i) subjecting a pyripyropene compound of formula Pyripyropene A to an alkaline hydrolysis to yield a 1,7,11-trideacetylpyripyropene A, ii) reacting 1,7,11-trideacetylpyripyropene A obtained in step i) with cyclopropane carbonyl chloride to yield a raw product containing the pyripyropene compound of formula (I); iii) subjecting the raw product of step ii) to crystallization to yield a crystalline pyripyropene compound of formula (I) and a mother liquor;and iv) recycling the mother liquor or a pyripyropene compound containing fraction thereof to the alkaline hydrolysis of step i).
