Methodology for preparing a series of novel alpha-amino-acids and thei
r derivatives containing an isoxazole ring as a substituent is present
ed. The synthesis starts from a readily available L-serine derivative
from which, depending on the synthetic strategy, it is possible to obt
ain isoxazol-3-yl or isoxazol-5-yl amino-acid precursors. (C) 1998 Els
