ABSTRACT:
Novel 4-cyano-3-hydroxybutanoyl hydrazides (10), particularly R-chiral intermediates are described. The intermediates are useful in preparing (R)-3-hydroxy-4-trimethylaminobutyric acid (L-carnitine) and R-4-amino-3-hydroxybutyric acid (GABOB) and chiral chemical intermediates which are medically useful.
