The high reactivity of 1d is probably due to electron-donating ability of the tert-butyl group, which accelerates proton addition to the α-carbon (step 2 in Scheme 1). The phenyl group of 1a or 1c would rather act as an electron-withdrawing substituent and reduce the reactivity of the double bond toward protonation. Mayr, H.; Patz, M. Angew. Chem., Int. Ed. Engl. 1994, 33, 938.

We have shown that the cyclization of 1 (R = H) to 3 proceeds in a syn addition mode of the hydroxyl group and proposed the oxonium ion intermediate from the stereochemical outcome. See ref 5.

There is a longstanding dispute on the structure of β-silyl carbenium ions, which can take a hyperconjugatively stabilized open form or a bridged form. Although the open forms 7 and 8 are employed in Scheme 1, when R is an alkyl group, they can be displaced to one bridged intermediate without any problems. Lambert, J. B.; Zhao, Y. J. Am. Chem. Soc. 1996, 118, 7867.

Although the fast cyclization of 8 compared with 7, that is, kinetic control, can be responsible for the exclusive formation of trans-2d, we do not have any reliable evidence that trans-2d is a kinetically favored product.

The MM2 calculation of the steric energy using the CAChe system (Sony/Tektronix Co. Ltd.) indicates that trans-2d is more stable by 3.5 kcal/mol than (2R*,1′S*)-3d in their optimized structures.
