摘要
We have investigated methods to monofluorinate the methyl positions 19 and 20 in retinal, and we describe a general, mild strategy that proceeds in high yields and is compatible with current carbon-13 labeling strategies. The new sequence consists of the conversion of N-methoxy-N-methylamides via the alpha-chloromethyl ketone to the corresponding gamma-hydroxy nitrile, which can subsequently be fluorinated by (diethylamido)sulfur trifluoride (DAST).
