DIASTEREOSELECTIVE SYNTHESIS OF THE TRANS-ANTI-CIS-DECAHYDRO-AS-INDACENE RING-SYSTEM VIA THE TRANSANNULAR DIELS-ALDER REACTION OF A FUNCTIONALIZED (E,E,E)-CYCLODODECA-1,6,8-TRIENE
Wr. Roush et Ab. Works, DIASTEREOSELECTIVE SYNTHESIS OF THE TRANS-ANTI-CIS-DECAHYDRO-AS-INDACENE RING-SYSTEM VIA THE TRANSANNULAR DIELS-ALDER REACTION OF A FUNCTIONALIZED (E,E,E)-CYCLODODECA-1,6,8-TRIENE, Tetrahedron letters, 37(45), 1996, pp. 8065-8068
A stereoselective synthesis of trans-anti-cis decahydro-as-indacene 5
is described. The key step of this synthesis is the tandem Claisen rin
g contraction of the 16-membered macrolactone 3 followed by the transa
nnular Diels-Alder reaction of the resulting (E,E,E)-cyclododeca-1,6,8
-triene 4. Copyright (C) 1996 Elsevier Science Ltd
