I have a compund containing an aldehyde and two methylesters, which I'm
doing reductive amination on.
This works fine with ordinary amines (even very steric hindred ones) using
Mol. Sieves / MeOH/amine and then NaBH4 or pyridine-BH3 (r.t.).
However when the amine is a BOC-protected hydrazine (t-Butylcarbazate,
BOC-NH-NH2) the reductive reagent doesn't seem to bee strong enough. Do you
have any suggestions for this transformation?
R-O-CH2-CHO + NH2-NHBOC -> R-O-CH2-CH2-NH-NHBOC
R containing methyl esters
