nucleophiles in organic transformations, which significantly expands the scope of synthetically accessible organosilicon compounds compared to previously reported methods. Thus, the present study can be expected to inspire the development of efficient methods for novel silicon-containing bioactive molecules and organic materials with desirable properties. We also report the first 11B1H} and 29Si1H} NMR spectroscopic
Various 3-sila derivatives of L-ascorbic acid were synthesized in satisfactory yields. The ether link was formed by an unusual aspect of the Mitsunobureaction, without the need of protecting the remaining hydroxy groups.
