The catalytic effects of poly(3-methyl-l-vinylimidazolium iodide) poly(3-n-hexadecyl-l-vinylimidazolium iodide), and their monomeric analogs on the alkaline hydrolysis of a series of neutral and anionic nitro-phenyl esters were studied in order to elucidate the contribution of hydrophobic and electrostatic interactions to their esterolytic efficiency. 

However, Borden and Smithi have found that treatment of the p-nitro-phenyl esters of 2 -deoxyribonucleoside 3 - and 5 -phosphates and of ribo-nucleoside 5 -phosphates with potassium fert-butoxide in methyl sulfoxide affords the corresponding nucleoside 3 5 -cyclic phosphates in excellent yields. Other phosphorus-activated nucleotides, such as nucleoside 5 -phosphorofluoridates, 5 -(2,4-dinitrophenyl phosphate)s and 5 -(PS-P " diphenyl pyrophosphate) s, were also cyclized to nucleoside 3 5 -cyclic...

Another related method uses the anion of nitroalkanes in a reaction with halo-esters. Nitromethane reacted with lithium diisopropylamide to form the nitro enolate and then with methyl 3-chloropentanoatc to give 4.110. Reduction of the nitro group with ammonium formate gave methyl 2-phenyl-3-aminopropanoate, 4.111. 

Nitrones or aci-nitro esters react with alkenes to give in some cases A/-substituted isoxazolidines and in others 2-isoxazolines. When the intermediate isoxazolidines were observed, a number of procedures transformed them into the 2-isoxazolines. Acrylonitrile and phenyl rzcf-nitrone esters produced an A/-methoxyisoxazolidine. Treatment with acid generated a 2-isoxazole while treatment with base generated an oxazine (Scheme 118) (68ZOR236). When an ethoxycarbonyl nitrone ester was reacted with alkenes, no intermediate isoxazolidine was observed, only A -isoxazolines. Other aci-mtro methyl esters used are shown in Scheme 118 and these generate IV-methoxyisoxazolidines or A -isoxazolines which can be further transformed (72MI41605).
