P. Merino et al., Synthesis of isoxazolidin-5-ones via stereocontrolled Michael additions ofbenzylhydroxylamine to L-serine derived alpha,beta-unsaturated esters, TETRAHEDR-A, 9(22), 1998, pp. 3945-3949
The synthesis of optically active isoxazolidin-5-ones from alpha,beta-unsat
urated esters is reported. The key features of this synthetic sequence incl
ude the stereocontrolled Michael addition of benzylhydroxylamine to alkenes
7 and 8 and the intramolecular cyclization to the target compounds (C) 199
