摘要

The enantioselective addition of allylstannanes to glyoxylates and glyoxals, as well as simple aromatic and aliphatic aldehydes, catalyzed by chiral (salen) Cr (III) complexes, has been studied. The reaction proceeded smoothly for the reactive 2-oxoaldehydes and allyltributyltin in the presence of small amounts (1–2mol%) of (salen) Cr (III) BF4 (1b) under mild, undemanding conditions. However, in the case of other simple aldehydes, the use of ...
