Preparation of fumaraldehydic acid and some of its derivatives: Preparation of fumaraldehydic acid and some of its derivatives. Scharf, Hans Dieter; Janus, Joachim (Inst. Org.Except for chemicals metioned above, 2833-30-9 is also used. Chem., Tech. Hochsch. Aachen, Aachen, Ger.). Chem. Ber., 111(7), 2741-4 (German) 1978. CODEN: CHBEAM. ISSN: 0009-2940. DOCUMENT TYPE: Journal CA Section: 23 (Aliphatic Compounds) Fumaraldehydic acid was prepd. in 58.5% yield by thermal isomerization of malealdehydic acid. The prepn. of ester acetals and esters of both compds. starting from fumaraldehydic acid was described. The derivs. prepd. are useful basic materials in the synthesis of natural products. .
