T7ze regioseZectivity of the EtAlCZ -cataZyzed addition of methyl vinyl ketone to the titZe diene can be reversed by solvent modz &cation. 9 The chemical properties of the diene moieties in 2,3-bis(methylene)bicycloC2.2.l]alkanes can be affected by remote substitution at C(5) and C(6).' For example

An qJ?cient method has been developed for the stereoselective substitution of ## 7-oxabicyclo[2.2.l]hept-2-yl derivatives by protected amino group at C(S-exo) and hydroxy group at C(6-endo). The 7-oxabicyclo[2.2.1]hept-S-en-2-yl derivatives 1 -6 can be obtained optically pure.' Because of their b
It was established that exclusively high regioselective C O bond cleavage of 7-oxabicyclo[2.2.1]heptane skeletons, which are unique Diels-Alder products of furans, under mild conditions using samarium(II) iodide and samarium powder yields cyclohexanol derivatives or aromatic compounds.
