Syntheses and Biological Activities of Octahydro-1H-cyclopenta[d]pyrimidine Derivatives
摘要:
Various nitromethylene derivatives were synthesized regioselectively. Compounds 8a-f were obtained by the reaction of 1-((5-chloropyridin-2-yl)methyl)-2-(nitromethylene)-octahydro-1H-cyclopenta[d]pyrimidine (3) with primary amines and formaldehyde. The synthesized compounds were identified by H-1 NMR, HRMS (EI), and IR, and preliminary bioassays indicated that most of them showed moderate insecticidal activities against Aphis craccivora. The relationship between hydrophobicity and biological activity was also discussed.

The invention relates to the field of separation by distillation of 6-aminocapronitrile (ACN) and hexamethylenediamine (HMD) from a mixture comprising ACN, HMD, tetrahydrozaepine (THA), adiponitrile (ADN) and low boilers (LB). A method for producing a distillate stream comprising HMD is disclosed, which is suitable for the production of Nylon-6,6. The tails stream from the distillation of the mixture can be further distilled to produce a distillate comprising ACN and THA, which is particularly suitable for use in the production of caprolactam and Nylon-6 from the caprolactam. Process conditions of the method of the invention disfavor the production of 2-cyanocyclopentylideneirnine (CPI).
The invention relates to a method for producing hexamethylenediamine, wherein a) a muconic acid starting material is provided, which is selected from among muconic acid, esters of muconic acid, lactones of muconic acid, and mixtures thereof, b) the muconic acid starting material is subjected to a reaction with hydrogen in the presence of at least one hydrogenation catalyst in order to form 1,6-hexanediol, and c) the 1,6-hexanediol obtained in step b) is subjected to amination in the presence of an amination catalyst in order to obtain hexamethylenediamine. The invention further relates to hexamethylenediamine which can be produced by means of said method.
