Pj. Dunn et al., Tandem 1,3-azaprotiocyclotransfer-cycloaddition reactions between aldoximes and divinyl ketone. Remarkable rate enhancement and control of cycloaddition regiochemistry by hafnium(IV) chloride, CHEM COMMUN, (20), 2000, pp. 2035-2036
The tandem 1,3-azaprotiocyclotransfer-cycloaddition reaction between aldoxi
mes and divinyl ketone affords the exo- isomers of substituted 1-aza-8-oxab
icyclo[3.2.1]octan-4-ones when a substoichiometric amount of hafnium(iv) ch
loride is added.
