analogue of the grapefruit odorant rhubafuran (1a), was synthesized and isolated as a 1:1 mixture of two racemic diastereomers. In addition, the structurally related racemic C/Si pairs 2a/2b and 3a/3b were prepared. To get information about structure–odor relationships in the domain of grapefruit odorants, the C/Si pairs 1a/1b, 2a/2b, and 3a/3b were studied for their olfactory properties.

First sila-functional heterocycles 7 and 9 with Si and S atoms in 1,3-position bearing the reactive X group at silicon (X = i-PrO, F) were readily prepared from the corresponding phenyl-protected cycle 6 in good yields via Ph-Si bond cleavage by electrophilic reagents. Treatment of i-propoxy derivative 7 with LiAlH(4) gave heterocycle 8 with Si-H bond. (C) 2009 Elsevier B.V. All rights reserved.
