ChemInform Abstract: REACTION OF A PREGNENO(16,17‐D)ISOXAZOLE WITH THE METHYL ESTER OF FLUOROSULFONIC ACID

N-hydroxy .alpha.-amino acids in organic chemistry

“…72 Without reduction this method leads to an oxazolidinecarboxylic acid derivative having an a-hydroxy function. 73 Another method for the synthesis of an oxazolidinecarboxylic acid derivative starts with cycloaddition of nitrones to alkenes. This method has been ingeniously applied for the synthesis of a biologically active proline analogue (eq 21).…”
