Anthracene derivativesQ 1080 Cyclohexenones as Michael Acceptors in the Staunton—Weinreb Annulation:

A Simple Stannane Modification for the Synthesis of Polycyclic Systems. — The stannane (I) is transferred easily to the corresponding toluate anion, which reacts with a variety of chiral and nonchiral cyclohexenones. Complex polycyclic systems are obtained in good yields and some of them are of biological interest. — (HILL, B.; RODRIGO*, R.; Org. Lett. 7 (2005) 23, 5223-5225; Dep. Chem., Univ. Waterloo, Waterloo, Ont. N2L 3G1, Can.; Eng.) — R. Steudel
