A novel approach to the synthesis of diaza-bridged heterocycle derivatives
摘要:
A novel synthetic route of diaza-bridged heterocycles based on natural 3,9-diazabicyclo[3.3.1]non-6-ene scaffold has been accomplished. The synthetic approach consists of a Pictet-Spengler condensation of the L-Dopa-OMe with an appropriate aldehyde, Fmoo-Aa-H, followed by intramolecular lactamization. This approach generated two configurationally distinct products (cis and transisomers), increasing the stereochemical diversity of these compounds. The synthesized compounds are potentially useful in the discovery of novel pharmacologically active compounds. (c) 2006 Elsevier Ltd. All rights reserved.
