First synthesis of (+)-rengyolone and (+)- and (−)-menisdaurilide
摘要:
The benzofuranone natural products (+)-rengyolone and (+)- and (-)-menisdaurilide have been synthesised for the first time from a common enantiopure cyclohexane building block derived from a monoketal of p-benzoquinone. (C) 2002 Elsevier Science Ltd. All rights reserved.

We report herein the first totalsynthesis of (-)-incarviatone A (1) in 14 steps starting from commercially available inexpensive phenylacetic acid (9). Our early stage synthesis relies on the scalable and sequential C-H functionalization to rapidly assemble the indanyl dialdehyde framework. Further biomimetic cascade strategy allows us to obtain the natural product in a one-pot operation. We also

Pick one out of three: Acyclic and cyclic 1,2,3‐triols are silylated with exceptional site‐ and enantioselectivity by a small‐molecule catalyst to afford silyl ethers having a neighboring diol moiety. The new process is applied to the enantioselectivetotalsyntheses of three cleroindicins, natural products isolated from a plant used in China to battle malaria and rheumatism.

Starting from a common, easily available, enantiopure monoketal of p-benzoquinone, the synthesis of a large number of cyclohexane chirons has been achieved. The first synthesis of (+)-rengyolone and (+)- and (-)-menisdaurilide has been performed from one of these new building blocks. The wide variety of functional groups of this series of chirons makes them useful for subsequent synthetic processes. (C) 2003 Elsevier Science Ltd. All rights reserved.
