Biomimetic Synthesis of Polyketide Aromatics from Reaction of an Orsellinate Anion with Pyrones and a Pyrylium Salt

Orsellinate anion (12) shows highly regioselective attack on pyrones (13), (22), and (30), and the products were simply converted into derivatives of the polyketides: toralacton (19), 6-hydroxymusizin (26), and eleutherinol (32); although reaction of the anion (12) with the pyrylium salt (33) is less selective, the minor product (34) can give derivatives of either alternariol (36) or rubrofusarin (37) in regiospecific biomimetic reactions.
