Reaction Steps
A solution of diethyl 2-furanphosphonate (1 mmole) in THF was treated with LDA (1.12 mmole, lithium N,N-diisopropylamide) at −78° C. for 20 min. Methyl formate (1.5 mmole) was added and the reaction was stirred for 1 h. Extraction and chromatography gave compound 1 as a clear yellow oil. Preferably this aldehyde can be prepared from 2-furaldehyde as described below.
