Application

Methyl formate may be used in the synthesis of the following building blocks:
  • methyl 4-chloro-2-formylbutanoate from methyl 4-chlorobutanoate via -formylation
  • potassium methyl α-[(methoxyethylidene)amino]-β-hydroxyacrylate from methyl α-[(methoxyethylidene)amino]acetate
  • (S)-(-)-1-formyl-2-hydroxymethylpyrrolidine from (S)-(+)-2-hydroxymethylpyrrolidine via N-formylation
