2 intramolecular Diels−Alder reaction has been developed. Microwave irradiation of the trienes provides a convenient method for the synthesis of bridgehead alkenes. Higher yields, shorter reaction times, and lower reaction temperatures provide a general and efficient route to this interesting class of molecules.

type two intramolecular Diels-Alder reaction (T2IMDA) is an efficient method for the formation of medium rings. The methodology is particularly effective for the construction of seven- and eight-memberedrings. A strategy for the synthesis of functionalized cycloheptanes and cyclooctanes has been developed that involves a bridged to fused ring interchange. The T2IMDA provides a synthesis for rigid
