Synthesis of (+/-)-kadsurenone (1), (+/-)-denudatin B (2), (+/-)-O-methyl-liliflodione (3a), and (+/-)-liliflol B (14) is described. The key synthetic step is a biomimetic cationic cycloaddition between E- or Z-1,2-dimethoxy-4-propenylbenzene (11) and ortho-quinone monoketal 10. (C) 1999 Elsevier Science Ltd. All rights reserved.
