Abstract

The spiroacetal [C(9)-C(20)] fragments of spirofungins A and B, antibiotics isolated from Streptomyces violaceusniger Tü 4113, were prepared from a known bromo alcohol derived from (S)-citronellal, using thermodynamically controlled iodolactonization and spiroacetalization as the key steps.
