Reductive amination is usually a one-pot procedure during which a carbonyl compound is reacted with ammonia or a primary amine to yield an imine. Subsequently the imine is reduced in situ to an amine. The procedure has application in synthesis of biologically active molecules. In this experiment the imine will be prepared quantitatively through a solvent free reaction (green chemistry) between ortho-vanilin and para-toluidine. The imine is...

1. Reductive amination (Carey, Section 22.10) is an important C-N bond forming strategy widely used in the synthesis of biologically active natural product. It's a powerful and reliable strategy that avoids the problem of overalkylation that often accompanies direct alkylation of amines with alkyl halides (Figure 1). secondary amine r tiary amine quemary sa Figure 1: Yields are generally poor as product amines are more nucleophilic and can also react with halide. The result is often a mixture of amines...

The acetoacetic ester synthesis is a carbonyl alkylation reaction. It is used to prepare methyl ketones from primary alkyl halides, lengthening the carbon chain by three atoms. Thus, the product can be visualized as being a "substituted acetone." The reaction consists of three steps: generation of the enolate anion followed by S2 reaction with a primary alkyl halide, ester hydrolysis under acid conditions, and decarboxylation. 1. NaOEt 2.

You have laboratory data on all the compounds in the
synthesis, however the amount of data available to you varies. Some
have the entirety of the spectral data, others have as little as
the elemental analysis. Use the laboratory data to help you
discover which reaction has been performed.
