Functionalized templates for the convergent assembly of polyethers: synthesis of the HIJK rings of gymnocin A.
Extension ladder: The successful application of epoxide-opening strategies towards the synthesis of ladder-type polyethers is contingent upon further elaboration of the product. By employing two different functionalized templates, a fragment of gymnocin A that bears four sites for subsequent fragment coupling has been prepared (see scheme; Bn = benzyl).
