The subject of the invention is the use of chiral (1R, 2R)-diaminocyclohexane derivative with a taddol substituent for the treatment and prevention of herpes type 1, by inhibiting the replication of HSV 1 virus.
Mannich-type reactions of a chiral bicyclic imine and various nucleophiles yield the corresponding adducts with good to high diastereoselectivity. The influence of the reaction conditions on the yield and stereochemical outcome is investigated. The configuration of the products is established by H-1 NMR spectroscopy, and the major isomers of two adducts are characterized by X-ray crystallography. (C) 2014 Elsevier Ltd. All rights reserved.
Monoimine Derived from <i>trans</i>-1,2-Diaminocyclohexane and Ethyl Glyoxylate: An Intermediate in Aza-Diels–Alder and Mannich Reactions
Novel enantiopure policyclic nitrogen heterocycles have been obtained in the diastereoselective aza-Diels-Alder or Mannich reaction of dienes with imine formed in situ from ethyl glyoxylate and (1R,2R)-diaminocyclohexane.

A series of new aminophosphonate and phosphonic acid derivatives of hexahydroquinoxalin-2(1H)-ones and tetrahydroquinoxalin-2(1H)-ones were synthesised via hydrophosphonylation of the corresponding bicyclic imines with various dialkyl or diaryl H-phosphonates, H-phosphinates or H-phosphine oxides as phosphorus nucleophiles. The utility of the obtained compounds was demonstrated by their application

New chiral bicyclic imines, enamines and amines were prepared via Horner–Wadsworth–Emmons reaction of hexahydroquinoxalin-2(1H)-one-derived phosphonate, as the source of a phosphonate carbanion, and a wide range of structurally diverse carbonyl substrates. The simplicity of the synthetic protocol, high selectivity, and broad substrate scope are the main advantages of the presented methodology.
