Abstract
Syntheses of numerous 2-aryl nitroethylenes (nitrostyrenes) have been optimized. The nitrostyrenes have been reacted with cyclopentadiene in Diels–Alder cycloadditions and the 3-aryl 2-nitronorbornenes obtained have been reduced into 3-aryl 2-aminonorbornenes. These compounds are potentially dopaminergic molecules. The stereochemistry of the adducts obtained in the Diels–Alder reaction has been determined by 1H nmr. The stereochemistry and the relative reactivity of the nitrostyrenes versus cyclopentadiene have been confirmed by theoretical calculations based on the CNDO/II method.This publication has 0 references indexed in Scilit:
