WebThe reactivity of alkynyl and enynyl Fischer carbene complexes towards 8-azaheptafulvenes is examined. Alkynyl carbenes 1 a-f undergo regioselective [8+2] heterocyclization with 8-aryl-8-azaheptafulvenes 2 a, b providing cycloheptapyrroles 3 and 4 with metal carbene or ester functionality at C3. Moreover, consecutive cyclization … WebA Fisher Indole Synthesis approach to Phidianidine Analogues. Naturally occurring products are molecules that are found in the natural world without the aid of humans. Aspirin and opium are famous examples of this classification of molecule. Another example of natural products that are less known are the phidianidines.
