What is Product 316393, Sodium triacetoxyborohydride, used for?
Sodium triacetoxyborohydride (NaBH(OAc)3) is particularly effective in reductive aminations due to its large scope, mildness, and selectivity.
Which is better to use, Product 316393, Sodium triacetoxyborohydride, or sodium cyanoborohydride?
It is preferred to sodium cyanoborohydride (NaBH3CN) in many applications due to reduced toxicity of the side products formed, and better yields and reproducibility during synthesis. (See Chemfiles, vol 5, no. 9).   The reductive aminations of complex substrates also proceed smoothly using sodium triacetoxyborohydride.You can access ChemFiles by clicking the following link: http://www.sigmaaldrich.com/Area_of_Interest/Chemistry/Chemical_Synthesis/Key_Resources/ChemFiles/Chemfiles_US.html
How else can Product 316393, Sodium triacetoxyborohydride, be used as a reducing agent?
Recently, sodium triacetoxyborohydride was used to stereoselectively reduce    4-ketoprolines to the corresponding trans-hydroxy-proline in excellent yields.  By comparison, reduction of the 4-ketoproline esters failed to provide any product.
