synthesized and studied for their olfactory properties. All of the silanes studied exhibit at least one of the main patchouli odor descriptors ‘woody,’ ‘earthy,’ and ‘camphoraceous,’ and some even exhibit all of them. The silanes MeR2SiC(OH)Me2 (12) and R3SiC(OH)Me2 (14) (R=cyclopropyl) were found to resemble natural patchouli oil most closely, with an even lower odor threshold than the natural lead
