Another synthesis of vertaline (61) involves an intermolecular [3 + 2] cycloaddition of nitrone 19 as a key step (Scheme 9) (27, 22). Ullmann reaction of bromide 82 with 79 in the presence of a phase-transfer catalyst such as tetra-butylammonium bromide gave the diphenyl ether 83 in about 50% yield. The cycloadduct 84 was prepared in 99% yield by heating 83 with the nitrone 19 in refluxing toluene. Treatment of 84 with methanesulfonyl chloride afforded an in-...
