A New Synthesis of Alloptaeroxylin, Its Methyl Ether and Related Compounds

Claisen condensation of 6-acetyl-5,7-dihydroxy-2,2-dimethylchroman (I) with sodium and ethyl acetate gives isoheteropeucenin (II) and isopeucenin (III).Benzylic bromination of II and III with NBS followed by dehydrobromination with pyridine affords alloptaeroxylin (IV) and dehydroisopeucenin (V) respectively.IV on methylation gives alloptaeroxylin methyl ether (VI).VI has also been synthesized by an alternate route.
