Abstract

I. TAPIA, V. ALCAZAR et JR MORAN. Can. J. Chem. 68,2190 (1990). On a prCparC des chromanes avec des rendements modestes en utilisant le salicylate de mtthyle et les dianions des dimtthylhydrazones des acides pyruvique ou a-oxobutyrique comme produits de dtpart. Mots clis : chromane, acide pyruvique, dimtthylhydrazone, dianion. ... We have recently found that the dianion of pyruvic acid dimethylhydrazone 1 is a strong nucleophile, which reacts ... After acid work-up and ...
