, p. 777 - 781 (1996)
Cyclisation of maleamic acids with acetic anhydride in dimethylacetamide (DMA) at ca. 75°C, with or without added cobalt naphthenate, gives predominantly maleimides when the parent maleic anhydride is unsubstituted. However, when the maleic anhydride has

Eight N-phenylalkylmaleimides (four 2-methyl-N-phenylalkylmaleimides and four 2,3-dimethyl-N-phenylalkylmaleimides with an alkyl chain (CH2)n (n = 1-4) between the imide N and the benzene ring) were subjected to biotransformation usi

A practical method for the multigram scale selective cis-dihydroxylation of electron deficient alkenes such as diethyl fumarate and N-alkyl and N-aryl-maleimides using H2O2 is described. High turnovers (>1000) can be achieved with this efficient manganese based catalyst system, prepared in situ from a manganese salt, pyridine-2-carboxylic acid, a ketone and a base, under ambient conditions. Under optimized conditions, for diethyl fumarate at least 1000 turnovers could be achieved with only 1.5 equiv. of H2O2 with d/l-diethyl tartrate (cis-diol product) as the sole product. For electron rich alkenes, such as cis-cyclooctene, this catalyst provides for efficient epoxidation.
