| titleOfInvention | Method for synthesizing N' - [ (2S,3S) -2- (benzyloxy) pentan-3-yl ] formylhydrazine |
| abstract | The invention discloses a method for synthesizing N' - [ (2S,3S) -2- (benzyloxy) pent-3-yl ] formhydrazide, which comprises the steps of reacting (S) -2-benzyloxy propionic acid with ethylenediamine to obtain (S) -2- (1-benzyloxy ethyl) -4, 5-dihydro-1H-imidazole; adding metal sodium into (S) -2- (1-benzyloxyethyl) -4, 5-dihydro-1H-imidazole under the protection of nitrogen, stirring and reacting to obtain (S) -2-benzyloxypropanal; reacting (S) -2-benzyloxy propionaldehyde with formylhydrazine, and carrying out post-treatment to obtain (S) -N' - (2-benzyloxy propylene) formylhydrazine; reacting (S) -N '- (2-benzyloxy propylene) formylhydrazine with a Grignard reagent, and carrying out post-treatment after the reaction is finished to obtain the product N' - [ (2S,3S) -2- (benzyloxy) pentan-3-yl ] formylhydrazine. Has the advantages of no use of expensive and unsafe organic aluminum compound, low preparation cost, simple post-treatment and simple and convenient operation. |
