O-Trimethylsilyl protected (R)-cyanohydrins 3 react with Reformatsky reagents from tert-butyl 2-bromoesters 4 and zinc dust (Blaise reaction) to give the corresponding addition products in high yields. Workup with an aqueous solution of NH4Cl at low

(4R)-3-Amino-4-trimethylsilyloxy-2-alkenoates (R)-3, obtained from O-trimethylsilyl protected optically active cyanohydrins (R)-1 via the Blaise reaction, are hydrolyzed under mildly acidic conditions to give optically active tetronic acids (R)-4 wit

Vinyl substituted (1 R ,2 S )-amino alcohols 5 were obtained by addition of vinyl magnesium bromide to the corresponding cyanohydrin O -trimethylsilyl ethers (R)- 2 . The O - and N -protected vinyl amino alcohols 6 were ozonized at −78°C in methan
