  Efficient Synthesis of the C₁−C₁₁ Fragment of the Tedanolides. The Nonaldol Aldol Process in Synthesis

  摘要：

  [GRAPHICS]The nonaldol aldol process developed in our laboratories has been applied to the synthesis of a C-1-C-11 fragment 22 of the novel macrocyclic cytotoxic agents tedanolide and 13-deoxytedanolide 1 and 2. The commercially available hydroxy ester 7 was converted in 24 steps into compound 22 using two nonaldol aldol reactions.

• Use of the non-aldol aldol process in the synthesis of the C1–C11 fragment of the tedanolides: use of lactol ethers in place of tetrahydrofurans

  日期：2000.12

  The use of a lactol methyl ether 23 in place of the simple tetrahydrofuran 11 allows for the high yielding non-aldol aldol process to occur without concomitant tetrahydropyran formation (cf 13) to give the desired product 24 in good yield. (C) 2000 Elsevier Science Ltd. All rights reserved.
