Abstract:
Disclosed is the compound Me2Val-Val-MeVal-Pro-Pro-NHBzl. HCl. The compound is produced from Z-Val-Val-MeVal-Pro-OR , wherein Z and R have the meanings indicated in the description. The compound disclosed has anti-neoplastic properties.
Abstract:
A process is disclosed for preparing a mixture of 8E,10E-dodecadienol (Ia), 8E,10Z-dodecadienol (Ib), 8Z,10E-dodecadienol (Ic) and 8Z,10Z-dodecadienol (Id), H3C-CH=CH-CH=CH-(CH2)6-CH2-OH, (8E,10E = Ia), (8E,10Z = Ib), (8Z,10E = Ic), (8Z,10Z = Id) from 1,8-octandiol (II) which is transformed by a halogenating agent into (III): Hal-CH2-(CH2)6-CH2-OH, (III) is then reacted with (IV): H2C=CH-O-R, producing (V): Hal-CH2-(CH2)6-CH2-O-CH(CH3)-OR, which is transformed in the presence of magnesium with crotonaldehyde into (VI): H3C-CH=CH-CH(OH)-(CH2)8-O-CH(CH3)-OR. The alcohol protective group is split off from (VI) in the presence of an acid, at the same time as the hydroxyl function is eliminated. Also disclosed are intermediates for this process, and a process for fighting the fruit surface eating tortrix moth Cydia pomonella with this mixture according to the mating interruption method.
Abstract:
A process is disclosed for producing α-chlor-methylen-triorganylphosphorane carboxylic acid derivatives having the formula (I), in which R stands for C organic substituents; A stands for CN or CO-B; B stands for C or O organic residues that remain inert in chlorinating conditions, by chlorinating phosphoranes having the formula (II) with chlorine. Chlorination is carried out in the presence of a mineral base as hydrogen chloride acceptor, whereas chlorine and the base are synchronously but separately introduced into the reaction mixture according to their consumption. The products (I) obtained by this process represent important intermediates for plant protective substances.
