Literature References

Diels-Alder adduct of acrolein and cyclopentadiene. Can be used as protected form of acrolein, from which the double bond may be liberated by cycloreversion, e.g. in a useful synthesis of 2-vinylimidazole: Angew. Chem. Int. Ed., 22, 560 (1983):

Aldol condensation with formaldehyde, followed by crossed Cannizzaro reduction, gives norbornene-2,2-dimethanol, from can be thermolyzed to vinyl-1,1-dimethanol: Tetrahedron Lett., 3775 (1975). For a review of cycloreversion reactions in organic synthesis, see: Synthesis, 121 (1985).
