37 - 130Synthesis of Functionalized Optically Active Bicyclic and AngularlyFused Tricyclic Compounds from (l)-Menthone by Tin-MediatedVinyl Radical Cyclization. — Starting from l-menthone the derivatives(I) and (VI) can be prepared which are used to synthesize the l-menthonepropargylderivative (IV) and the spiromenthone propargyl compound (X),respectively. Their tin- mediated radical cyclization leads to the functionalizedoptically active title compounds (V) and (XI), respectively, which can serve asprecursor for the synthesis of triquinane derivatives. — (SHANMUGAM, P.;SRINIVASAN, R.; RAJAGOPALAN, K.; Tetrahedron 53 (1997) 17, 6085-6096;Dep.
