Abstract
Controlled addition of Grignard reagents to tartaric acid derived bis-Weinr eb amide 3 provides a facile, direct entry to desymmetrized 1,4-functionali zed-syn-2.3-diol intermediates 4 and to C-2-symmetrical 1,4-diketones 5. Th e synthetic versatility of this method is exemplified by short syntheses of the natural plant growth regulator 10 and the synthetically valuable cyclo octene derivative 13.
