Straightforward stereocontrolled synthesis of (2S)-2-hydroxymethylglutamic acid was achieved from (S)-pyroglutaminol, through a bicyclic silyloxypyrrole derived from the versatile unsaturated lactam 3.

Racemic deoxydysibetaine was efficiently obtained in few steps from methyl pyroglutamate. The 2S enantiomer was synthesized from (S)-pyroglutaminol as chiral starting material, through the key intermediate (S)-2-hydroxymethylglutamic acid recently prepared with complete stereoselectivity in our laboratory.
