[摘要]:The total synthesis of hirsutellones A (1), B (2), and C (3) has been achieved through a bloinspired late-stage sequence starting from advanced intermediate 6. The sequence proceeded via labile Intermediate 17,1'-dehydrohlrsutellone B (5) and delivered, In addition to the natural products (1-3), hirsutellone analogue 1',2',17-epi-hirsutellone C (1',2',17-epi-3). |
