Abstract:
Transannular Diels–Alder reactions of four 14-membered macrocyclic trienes (27, 28, 43, and 44) possessing a dimethyl tetrasubstituted dienophile have been investigated. Macrocycles having a cis-trans-cis (CTC) (27), a CTT (43), and a TTT (44) geometry produced the predicted trans-syn-cis (TSC) (45), cis-anti-cis (CAC) (48), and TAC (49) tricycles, respectively. The TTC macrocycle (28) gave exclusively the TST tricycle (46), no CSC tricycle (47) being observed. TTT macrocycle (44) underwent macrocyclization at a lower temperature than the TTC isomer (28).
