Ethyl quinolin-4-one-3-carboxylate has been converted in 4 steps into 4H-pyrano[3,4-c]quinolin- 4-one and 3-methoxyquinolin-4-one has been converted in 3 steps into 3H-pyrano[2,3-c]quinolin-3-one. Neither of these tricyclic lactones corresponds to natural cherimoline. (C) 1998 Elsevier Science Ltd. All rights reserved.
