摘要
A concise total synthesis of (+/-)-communesin F has been completed in 15 linear steps from 4-bromotryptophol in an overall yield of 6.7%. A key step features the cycloaddition of indol-2-one with 3-(2-azidoethyl)-4-bromoindole and facilitates the rapid construction of the lower aminal-containing tetracyclic core of the natural product.
