Studies Towards the Synthesis of the C29-C51 Fragment of Altohyrtin A
31 December 2000 (online)
The synthesis of the highly substituted E and F pyran fragment 23 of altohyrtin A 1 from tri-O-benzyl-d-glucal 5 is described. The synthesis of a model compound 31 containing the altohyrtin A triene side-chain outlines the proposed strategy for the elaboration of the F pyran.
