Cycloaddition of cyclohexa-2,4-dienones with electron deficient 2 pi partners: a novel and stereoselective route to functionalized bicyclo[2.2.2]octenones.
A novel route to functionalised bicyclo[2.2.2]octenones via pi 4s + pi 2s cycloaddition of cyclohexa-2,4-dienones with electron deficient 2 pi partners, and crystal structure of 1,7-dimethyl-5-hydroxy-5-chloromethyl-2-carboethoxy bicyclo[2.2.2]oct-7-ene-6-one, is reported.
