Abstract

The insertion of formamides into a C-Si bond of silirane trans- 1 provides a facile route to the oxasilacyclopentane acetate 5 (86% overall yield). Stereoselective carbon-carbon bond formation on the derived oxonium ion was achieved by addition of the silyl enol ether of acetophenone (92:8 selectivity, 79% yield) and 3-pentanone (92:5:3 selectivity, 100% yield). These results demonstrate the potential of siliranes as intermediates in organic synthesis.
