This limitation was initially treated by Sauer and is reinforced in recent reviews on the Diels-Alder reaction: Ciganik, E. Org. React. 1984, 32, 1. Fallis, A. G. Can. J. Chem. 1984, 62, 183. Taber, D. F. Intramolecular Diels-Alder and Ene Reactions; Springer-Verlag: Berlin, 1984. Brieger, G.; Bennett, J. N. Chem. Rev. 1980, 80, 63. The problems attending thermal dienyne cycloadditions have limited the number of examples of this process in synthesis. For some recent examples which provide calibration on the thermal requirements for such reactions, see: Shea, K. J.; Burke, L. D. J. Org. Chem. 1988, 53, 318. Kanematsu, K.; Hayakawa, K.; Yodo, M.; Ohsuki, S. J. Am. Chem. Soc. 1984, 106, 6735. Liu Z.-Y.; Zhou, X.-R.; Wu, Z.-M. J. Chem. Soc., Chem. Commun. 1987, 1868. Cyclization involving a deca-7,9-dien-1-yne was found to require 150 °C, 72 h, 89% (Trost, B. M. Stanford University, personal communication, 1988). Cyclizations involving nona-6,8-dien-1-ynes were found to require 150 °C, 5 h, 65-68% (Roush, W. R. Indiana University, personal communication, 1988).

For a general review, see: Recent examples of acetylene or general alkyne equivalents include the following: (trimethylsilyl)vinyl sulfone (Carr, R. C. V.; Paquette, L. A. J. Am. Chem. Soc. 1980, 102, 853), ethynyl sulfone (Davis, A. P.; Whitham, G. H. J. Chem. Soc., Chem. Commun. 1980, 639), vinyl sulfoxide (Paquette, L. A.; Moerck, R. E.; Harirchian, B.; Magnus, P. D. J. Am. Chem. Soc. 1978, 100, 1597), (E)-or (Z)-1,2-bis(phenylsulfonyl)ethylene (De Lucchi, O.; Lucchini, V.; Pasquato, L.; Modena, G. J. Org. Chem. 1984, 49, 596), maleic anhydride (Westberg, H. H.; Dauben, H. J. Tetrahedron Lett. 1968, 5123) and 1,4-benzodithiin-1,1,4,4-tetraoxide (Nakayama, J.; Nakamura, Y.; Hoshino, M. Heterocycles 1985, 23, 1119).
