M. Kodaka et al., Synthesis of a bicyclic transition-state analogue for the ene reaction between maleimide and allylbenzenes, ACT CHEM SC, 53(7), 1999, pp. 493-496
A bicyclic phenyldioxohexahydro-1H-isoindole-based hapten with a high simil
arity to the transition state of the ene reaction between maleimide and all
ylbenzenes has been designed and synthesized.
