Abstract :
A novel mild access to the (beta)-carboline skeleton is described. The reaction is a Bischler-Napieralski-type cyclocondensation, promoted by (PhO)3P·Cl2, which is performed in dichloromethane at -30 °C. The products are easily obtained in good yields and do not require further chromatographic purification.
