When the methyl protons and the methyne proton adjacent to the silicon were irradiated, NOEs as shown in Figure 1 were observed.

note
-
Although the stereochemistries of 9a and 9b were confirmed by the NOE data as shown in Figure 2, no NOE was observed when the silyl methyl protons of 10a or 10b were irradiated. Therefore, the configurations at the silicon of 10a and 10b were confirmed based on chemical shifts of the methyl groups attached to the silicon of the compounds having benzo-[f]-2-oxa-3-silabicyclo[3.3.0]octane or benzo[g]-2-oxa-3-silabicyclo[4.3.0]-nonane structure synthesized in this study: the signals of the exo-SiMe protons in 1b, 1d, 9b, and 10b (0.43-0.57 ppm) were observed at lower fields compared with those of the endo-SiMe protons in 1a, 1c, 9a, and 10a (-0.02-0.18 ppm) presumably due to deshielding by the benzene ring condensed with the 2-oxa-3-silabicyclo[3.3.0]octane or 2-oxa-3-silabicyclo-[4.3.0]nonane ring (see Figure 2).
