Addition of pentylmagnesium bromide to 4,4-dimethoxybut-2-enal gave 1,1-dimethoxy-4-hydroxynon-2-ene,resin-catalyzed hydrolysis of which afforded the final product(E)-4-hydroxynon-2-enal in overall yield of 8.

Effects of overexpression of X-linked inhibitor of apoptosis protein on nitrotyrosine and 4-hydroxy-2-noneal formation in hypoxia-ischemia brain of neonatal mice;

Effects of X-linked inhibitor of apoptosis(XIAP) protein on nitrotyrosine and 4-hydroxy-2-noneal formation following irradiation exposure in the developing brain;

Determination of trans-2-nonenal in beer by SPE-HPLC;

Ratio of trans-2-cis-6-nonadienal content to trans-2-nonenal is high during the early and middle stage of cucumber fruit development, it is low in old fruits.

The changes of trans-2-nonenal,DPPH(1,1-Diphenyl-2-picrylhydrazyl radical 2,2-Diphenyl-1-(2,4,6-trinitrophenyl) hydrazyl),reducing power,total polyphenol,yeast activity,and turbidity in yeast-containing beer during aging in 38℃ were studied in this paper.

A key intermediate for preparation of coenzyme Q10—trans-1-phenylsulfonyl-2-methyl-4-hydroxy-2-butene was synthesized by addition reaction of isoprene and phenylsulfonyl chloride,and subsequent acetolysis and saponification.
