Abstract
2D NMR spectroscopic data are reported for 6-hydroxyfurodysinin-O-methyl la ctone (3), 2-(2',4'-dibromophenoxy)-4,6-dibromo-anisole (4), and dehydroher badysidolide (8), all isolated for the first time from Dysidea sp. Revised NMR assignments are presented for the compounds dysetherin (1) and furodysi nin-O-methyl lactone (2), previously reported from Dysidea herbacea. The fu ll relative stereochemistry of spirodysin (12) is defined for the first tim e. (C) 2000 Elsevier Science Ltd. All rights reserved.
