Two new maleimide derivatives have been synthesized, prone to self-assemble and react with graphene as dienophiles. Both compounds bear a long alkyl chain on the carbon-carbon double bond position 3. The maleimide 1 bears a second alkyl chain at the nitrogen, while in compound 2, three maleimide functionalities are linked to a triethynylbenzene core.
A new route to (±)-erythro-roccellic acid and chaetomellic anhydride C through functional rearrangement, promoted by n-propylamine or CH3ONa/CH3OH, of N-propyl-3-chloro-4-dichloromethyl-3-dodecylpyrrolidin-2-one

The rearrangement of a trichloro-pyrrolidin-2-one, prepared by the CuCl–TMEDA catalyzed atom transfer radical cyclization of N-alkyl-N-(3-chloro-2-propenyl)-2,2-dichloromyristamide, with n-propylamine or CH3ONa/CH3OH, is the key step of a new, short and inexpensive route to chaetomellic anhydride C and (±)-erythro-roccellic acid.

derivatives 4-11. Hydrolysis with lithium hydroxide generated the corresponding lithium carboxylates, which readily closed to 2,3-disubstituted maleic anhydrides 17-20 upon acid treatment. Compound 16, an analogue wherein the tetradecyl group of 1 is replaced by a farnesyl moiety, is 7-fold more potent than 1 as an inhibitor of protein farnesyltransferase from yeast and displays a 100:1 selectivity for

Compounds and compositions for prodrugs useful for the oral and parenteral delivery of amine-containing drugs, amino acids, and peptides are described. Compounds containing biologically-active amino groups are conjugated to a lipophilic derivative through an amide bond in order to facilitate transport of the conjugate through the cell membrane. Methods of coupling a biologically-active molecule containing at least one amine functional group to a lipophilic anhydride are also described.
