Synthetic studies towards the total synthesis of tedanolide: formation of the C(13)–C(23) fragment
摘要:
The C(13)C(23) subunit of tedanolide was obtained using a boron-mediated aldol reaction as the key step to control the C-16, and C-17, stereocenters. (C) 2001 Elsevier Science Ltd. All rights reserved.

Tedanolide, which was isolated by Schmitz in 1984 from the marinespongeTedaniaignis, is a highly cytotoxic macrolide leading to strong growth inhibition of P338 tumor cells in bioassays. A unique structural feature of the known tedanolides is the primary hydroxyl group incorporated in the macrolactone. This unusual motif for macrolactones originated from PKS biosynthesis might arise through lactonizations
