T. Yoshinaga et al., A NOVEL MACRODIOLIDE SYNTHESIS USING THE MN(III)-BASED RADICAL CYCLIZATION OF TERMINAL ALKADIENES AND OLIGOMETHYLENE DI(3-OXOBUTANOATE)S, Tetrahedron letters, 39(50), 1998, pp. 9197-9200
pha,omega,omega-Tetraphenyl-alpha,omega-alkadienes reacted with oligom
ethylene di(3-oxobutanoate)s in the presence of manganese(III) acetate
at 100 degrees C under an argon atmosphere to give new 12 to 22-membe
red macrocyclic compounds which were two fused dihydrofuran rings in a
one-step procedure. (C) 1998 Elsevier Science Ltd. All rights reserve
