A concise diastereoselective synthesis of 5′-epi synargentolide-B
摘要:
A concise linear synthesis of 5'-epi synargentolide-B has been accomplished with i) catalytic asymmetric transfer hydrogenation for the genesis of chirality, ii) regioselective Sharpless asymmetric dihydroxylation iii) a vinylogous Mukaiyama aldol reaction to ensure 5,6-dihydro-2H-pyran-2-one reactions as pivotal steps.

Enantiospecific total synthesis and determination of the absolute stereochemistry of the α-pyrone-containing natural product synargentolide B were accomplished. The absolute stereochemistry of the natural product was established by synthesizing the possible diastereomers and comparison of the data with those reported for the natural product. During the process, total synthesis of the putative structure
