Synthetic studies of the ionophore antibiotic zincophorin. 2. Iterative sigmatropic construction of the C1–C11 subunit
摘要:
Advanced intermediates 22 and 23. representing the C1-C11 subunit of the ionophore zincophorin, have been prepared by a scheme incorporating sequential glycolate Claisen and [2,3] Wittig rearrangements to establish the key structural and stereochemical elements of the title compound.
