We have developed an efficient method to regioselectively deacetylate polyacetoxyacetophenones using BF3·OEt2 in excellent yields and demonstrated the application of the procedure in the synthesis of natural products.

(+/-)-Flemistrictin-E (I) has been synthesised by selective acetylation of the non-chelated hydroxyl of 3-C-prenylresacetophenone (III), treatment of the resulting IV with perbenzoic acid at 0 deg C in dry ether followed by chalcone condensation of the resulting ketone (V) with benzaldehyde. (+/-)-Flemistrictin-F (II) has been synthesised by treating 4-O-acetyl-3-C-prenylresacetophenone (IV) with perbenzoic acid in dry chloroform in the presence of p-toluenesulphonic acid followed by chalcone condensation of the resulting ketone (VI) with benzaldehyde.
