Uses
Morpholine, 2,6-diMethyl-, (2R,6R)- is an isomerizing agent that converts (2S,6S)-2,6-dimethylmorpholine to (2R,6R)-2,6-dimethylmorpholine.
Synthesis
Morpholine, 2,6-diMethyl-, (2R,6R)- was prepared efficiently by O-alkylation of (R)-ethyl lactate with the O-trifluoromethylsulphonyl derivative of (S)-ethyl lactate
[1].
