Partial synthesis of germacranolides with pyran and furan-type rings
摘要:
Pathways to synthesize germacranolides with ether bridges between C1 and C5 or C3 and C-10 were described. A joint precursor was prepared using a readily available and inexpensive compound as starting material. The key step in the preparation of dihydropyranone-germacranolides proved to be a one-pot procedure involving several transformations, induced by the iodotrimethylsilane/acetonitrile system.
