A series of 5-fluoro-t-4-[(Z)- and (E)-furfurylideneaminooxy]hexahydro-2, 6-dioxor-5-pyrimidinecarboxylates (6 and 7) was prepared by treatment of the corresponding 4-acetoxyhexa-hydropyrimidinecarboxylates 5 with (Z)- and (E)-furfuraldoximes (10 and 11), respectively, and tested for antitumor activity against murine colon carcinoma 26. The oxime ether 7c (TAC-788) showed antitumor activity against various murine tumors.
An iridium-catalyzed regioselective C–H borylation of pentafluoroaniline-derived heteroaromatic aldimines has been developed. Various heteroaromatic aldimines underwent borylation by bis(pinacolato)diboron to afford the corresponding borylated products in good yields in the presence of an iridium complex formed in situ from bis(cyclooctadienyl)(methoxy)iridium [Ir(OMe)(cod)]2} and 1,10-phenanthroline

Trichloroacryloyloxim-Derivate der Formel (1)
in der
R' ein Wasserstoff-Atom, eine niedere Alkyl-Gruppe, eine Phenyl-Gruppe oder eine 2-Pyridyl-Gruppe bezeichnet und
R2 eine, gegebenenfalls durch Methyl substituierte, monocyclische heterocyclische Gruppe mit wenigstens einem Hetero-Atom bezeichnet,
sind als landwirtschaftliche Fungizide wertvoll. Die neuen Trichloroacryloyloxim-Derivate können durch Reaktion eines entsprechenden Acylhalogenids bzw. Acylanhydrids mit einem geeigneten Oxim hergestellt werden.
