Solvent-Free Thermocyclization of the Unactivated Linear Gramicidin S Precursor and Analogues
摘要:
A convenient thermocyclization of the linear gramicidin S precursor and its analogues is demonstrated. With the preorganized beta-sheet conformation, the unactivated linear precursors can cyclize into the corresponding head-to-tail cyclic products in high yield after being heated under solvent-free conditions.
