The synthesis of racemic 5-iodo-6, 8-dimethoxy-1,3-trans-dimethylisochroman (16) in eleven steps from 2,4-dimethoxybenzaldehyde is outlined. Compound (16) was coupled by means of Suzuki methodology with 4-isopropoxy-5-methoxy-7-methylnaphthaleneboronic acid (19) to yield (20). This was converted into (6), a racemic isochroman analogue of the michellamines. (C) 1999 Elsevier Science Ltd. All rights reserved.
