摘要

O-Protected cyanohydrin derivatives constitute versatile intermediates in organic synthesis, 1 and several direct methods for their preparation have been reported so far. Cyanohydrin silyl ethers are prepared from carbonyl compounds with trialkylsilyl cyanide under the influence of Lewis acids, 2 Lewis bases, 3 or organocatalyst. 4 For cyanohydrin alkyl ethers, we recently demonstrated a convenient one-pot synthesis directly from aldehydes with trimethylsilyl ...
