Ag. Meyer et al., A CYCLODEXTRIN TO REVERSE THE REGIOSELECTIVITY OF NITRILE OXIDE CYCLOADDITION TO A TERMINAL ALKENE, Chemical communications, (16), 1997, pp. 1517-1518
The 1,3-dipolar cycloaddition of 4-tert-butylbenzonitrile oxide with 6
(A)-acrylamido-6(A)-deoxy-beta-cyclodextrin in aqueous solution favour
s formation of the 4-substituted isoxazoline, in contrast to the norma
l predominance of the 5-substituted regioisomer from reactions of mono
substituted alkenes.
