The TiCl4-catalyzed reaction of α-(phenylseleno)cycloalkanones with aldehydes gives aldol products with high threo selectivity.High stereoselectivity is also achieved in the formation of spiro aldol products starting with α-(phenylseleno)cycloalkanones bearing an aldehyde chain.
1,2-Addition of dimethyl(phenyl)silyllithium to cyclic α,β-unsaturated ketones and regiospecific generation of cyclic silyl enol ethers through Brook rearrangement of the 1,2-addition products

A highly convenient two-step sequence for the regiospecific synthesis of cyclic silyl enol ethers has been developed involving the 1,2-addition of dimethyl(phenyl)silyllithium to cyclic α,β-unsaturated ketones followed by the treatment of the resulting silyl carbinols with a catalytic amount of NaH in THF at 25°C.
