Beschreibung

Allgemeine Beschreibung

Benzyloxyacetone (α-Benzyloxyacetone) is an α-substituted acetone. It undergoes direct aldol reaction with 4-nitrobenzaldehyde in the presence of (S)-BINAM-L-prolinamide/benzoic acid to form predominantly the syn-diasteroisomer.

Anwendung

Benzyloxyacetone (1-Benzyloxy-2-propanone) may be used in the synthesis of:

• 7-benzyloxy-6-methyl-5-hepten-1-yne
• (Z)-2-methylhept-2-en-6-yn-1-o1
• (S)-(+)-1,2-propanediol, 1-benzyl ether

It may be used as a starting material in synthesizing (2S,4RS)-4-acetoxy-2-[(benzyloxy)methyl]-2-methyldioxolane and (2R,4RS)-4-acetoxy-2-[(benzyloxy)methyl]-2-methyldioxolane.
