2- 2- -2-alkenoate ester

The hydrogenation in the presence of Pd/G is also effective for the d compounds to amines. The Michael addition of nitromethime to 2-alkenoic esters followed by catalytic hydrogenation using 10% Pd/G in acetic acid md hydrolysis is a convenient method for the preparation of 3-alkyl-4-aminobut moic acids, which are importimt y-amino acids for biological snidy fEq. 6.48. The reduction c m be carried out at room temperanire md atmospheric pressure. [Pg.172]

A bifnnctional enol-CoA hydratase and 3-hydroxyacetyl-CoA dehydrogenase are used in the degradation of CoA-alkenoic esters to the p-keto acid. This is then degraded to acetyl-CoA and the lower alkanoate ester by 3-ketoacetyl CoA thiolase and acetyl-CoA thiolase. [Pg.118]

The 7-hydroxy-a,/3-( )-alkenoic esters were prepared readily from acid halides and silver acetylenides followed by NaBH4 reduction (Table 7).515... [Pg.477]

In addition to 1,2-alkyl shifts, sulfonium ylides with P-hydrogen can also undergo fragmentation into an olefin and a thioether [1317,1318]. When allylic thioethers are treated with two equivalents of ethyl diazoacetate in the presence of a catalyst for diazodecomposition, S-alkylation and elimination of the thioalkyl group from the initially formed a-alkylthio-4-alkenoic esters occurs to yield 2,4-dienoic esters [1319]. [Pg.214]
