Efficient Synthesis of a Configurationally Stable l-Serinal Derivative
摘要:
An efficient synthesis of a configurationally stable L-serinal derivative 8 was achieved using an N-hydroxymethyl group in about 50% overall yield in four steps from L-serine. Not more than 1% racemization was observed during the preparation of 8. Its enantiomeric integrity was maintained for at least 15 days at room temperature, and it was stable on silica gel. The orthogonal protective groups of 8 would make it a useful chiral synthon.

Two straightforward synthetic routes for the preparation of enantiomerically pure N-BOC-D-serinal acetonide (enantiomer of Garner's aldehyde) starting from naturally occurring L-serine are described.
