Synthetic studies on fully substituted γ-pyrone-containing natural products: Synthesis of γ-prone derivatives obtained by decomposition of peroniatriols

Arimoto,Nishiyama,Yamamura

, p. 5491 - 5494 (2007/10/02)

In connection with the two γ-pyrones obtained by decomposition reactions of peroniatriols I and II, γ-pyrone derivatives have been synthesized by newly developed mild cyclization methods, and this result revised the partial structures of these natural products.
