Abstract (en)
[origin: WO9529150A1] Prototype renin inhibitors having general structure (I), where n is 0-3 inclusive, A are either both hydrogen atoms or together are a single carbon-nitrogen bond, R1 is hydrogen, or hydrocarbylcarboxy wherein the hydrocarbyl entity is selected from the group consisting of alkyl of 1 to 6 carbon atoms or aralkyl of 7 to 10 carbon atoms, R2 and R3 or independently alkyl of 1 to 4 carbon atoms, R4 is alkyl of 1 to 6 carbon atoms or a substituent of aliphatic character such as, for example, butyl, 2-morpholinoethyl or 2-carbamoyl-2-methyl-propyl, R5 is selected from aromatics, substitued aromatics and heteroaromatics, substituted or unsubstituted cycloalkyls, cycloalkenes having 3 to 8 carbon atoms, with substituents selected from alkyl, alkoxy of 3 to 10 carbon atoms and alkoxy derivatives such as 3-methoxy-propyloxy, primary and secondary amides, alkyl derivatives, are prepared by novel multistep synthesis. Such compounds are valuable intermediates for the manufacture of pharmaceutical such as Renin inhibitors and HIV-protease inhibitors.
