Synthesis of unsaturated α-amino acids using the Ramberg–Bäcklund reaction
Abstract
A novel, and potentially versatile, procedure for the preparation of unsaturated α-amino acids in homochiral form is illustrated by the conversion of methionine into allylglycine (as its Boc, tert-butyl ester derivative) using the Ramberg–Bäcklund reaction in the key step.
