2-trimethylsilylethylidenetriphenylphosphorane (5) (Seyferth-Wittig reagent) reacts stereoselectively with the carbonyl compounds 6a-f to give the conjugated allylsilanes 7a-f, each as a mixture of E-and Z-isomers. The stereoselectivity of reactions of E-
Catalytic cyclometallation in steroid chemistry IV: Efficient method for the synthesis of tetrahydrothiophene, tetrahydroselenophen and cyclopentanone derivatives of (5α)-cholestane

Catalytic cycloalumination of (3β,5α)-3-vinylcholestane and (3α,5α)-3-allylcholestane with Et3Al catalyzed by Cp2ZrCl2 was performed for the first time to give previously unknown aluminacyclopentanes in ～90% yield; these p

Intramolecular anodic olefin coupling reactions can be compatible with the presence of dithioketal protecting groups even though the dithioketal oxidizes at a lower potential than either of the groups participating in the cyclization. In such cases, product formation is controlled by the Curtin-Hammett Principle. In this study, the generality of such reactions is examined along with the use of alternative reaction conditions to suppress unwanted side reactions.
