| الوصف: | Construction of structurally diverse carbazoles and bis-carbazoles by protecting-group-free formal [4 + 2]-benzannulation of 2-alkenyl indoles and aldehydes is demonstrated. The sequence of four different reactions is executed in one-pot using readily available and cheap bottle reagents as catalysts rendering this method attractive. The incorporation of inexpensive and environmentally benign molecular oxygen as the oxidant into the final aromatization step enables tolerance of several functional groups. |
