easily and efficiently from inexpensive and commercially available substrates. We tested this class of alkaloids in the alkylation of glycine derivative, carried out under phase-transfercatalyst conditions. The presented hybrid catalysts offer both high reaction yields (up to 97%) and high enantioselectivities of the obtained product (up to 94% ee).
Some tetracyclic compounds containing the pyridodiazepine system condensed with the pyridofuro, pyridothieno and indole groups were synthesized. In the case of indole derivatives the outcome of the reaction is highly dependent by the nature of the substituents.
