Double dioxanone-to-dihydropyran reorganization. Construction of a C(1)-C(13) erythronolide template

Burke,Lee,Santafianos

, p. 3957 - 3960 (1991)

Convergent, stereoselective construction of the lactate-derived bis(dioxananone) 16 and two concurrent [3,3] sigmatropic transformations thereof results in the trienic bis(dihydropyran) 2, a potential precursor of the intact C(1)-C(13) erythronolide array.
