✦ Synopsis

A 1:1 mixture of (N N)Pd(Me)Cl [N N=(R)-(+)-4-isopropyl-2-(2-pyridinyl)-2-oxazoline] (1) and NaBAr 4 [Ar=3,5-C 6 H 3 (CF 3 ) 2 ] catalyzed the asymmetric cyclization/hydrosilylation of functionalized 1,6-dienes with 1-tert-butyl-3,3-dimethyl-1,1-diphenyldisiloxane at -20°C to form silylated cyclopentanes in good yield with up to 95% ee. These silylated carbocycles underwent oxidative cleavage of the C Si bond with H 2 O 2 at room temperature to form the corresponding alcohols.
