Efficient syntheses of pterulone, pterulone B and related analogues
An efficient synthesis of the three halogenated naturally occurring products, pterulone (2), pterulone B (3) and alcohol 5, and of a wide range of related unnatural analogues has been achieved starting from the two readily available 1-benzoxepine sulfonyl-containing intermediates 6a and 6b. The biological activities of pterulone and some of the synthesized analogues were tested against a wide spectrum of phytopathogenic fungi.
