A Chiral Formamide: Design and Application to Catalytic Asymmetric Synthesis.-The first example of a chiral formamide that functions as a Lewis base catalyst for asymmetric addition of allylsilanes to aldehydes is described. Under the optimized conditions shown, enantioselectivities of up to 98% e.e. can be obtained. -(ISEKI, K.; MIZUNO, S.; KUROKI, Y.; KOBAYASHI, Y.; Tetrahedron

1999 stereochemistry stereochemistry (general, optical resolution) O 0030 -034Asymmetric Allylation with Chiral Formamide Catalysts. -Chiral formamide (BMF) mediates the enantioselective addition of silanes (II) and (XI) to aliphatic aldehydes in the presence of HMPA to provide the corresponding homoallylic alcohols in up to 98% enantiomeric excess. -(ISEKI,
