  Catalytic Diastereoselective Polycyclization of Homo(polyprenyl)arene Analogues Bearing Terminal Siloxyvinyl Groups

  摘要：

  Highly diastereoselective polycyclization of homo(polyprenyl) arene analogues bearing terminal siloxyvinyl groups was catalyzed by tin(IV) chloride (10 mol %). The cyclizations of tert-butyldiphenylsilyl and triisopropylsilyl polyenol ethers gave 4 alpha(equatorial)- and 4 beta(axial)-siloxypolycycles as major isomers, respectively. The strong nucleophilicity of pro-C(9), a (6E) geometry, and a bulky silyl group effectively favored the 4 alpha-preference, whereas the weak nucleophilicity of pro-C(9), a (6Z)-geometry, and less steric hindrance of a silyl group favored the 4 beta-preference.

• Tandem carbonyl ene cyclization-cycloalkylation: a route to trifluoromethyl diterpenoids.

  A new sequential carbonyl-ene cyclizatian/cycloalkylation of trifluoromethyl ketones catalyzed by aluminum Lewis acids is described. From ketone 1, the 4-CF3-4-OH cis-octahydrophenanthrene 6 is obtained in 50 % yield. From ketone 2, with MeAlCl(2) a total stereoselective route to the 4-CF3-trans-10-methyl podocarpatrienol 8 (90 % yield) has been found. These studies also exhibited some striking results in the stereochemical outcome of ene cyclizations.
