Rt. Brown et al., SYNTHESIS OF A MORPHINE-6-GLUCURONIDE HAPTEN, N-(4-AMINOBUTYL)NORMORPHINE-6-GLUCURONID AND RELATED HAPTENS, Tetrahedron letters, 36(47), 1995, pp. 8661-8664
For use as a hapten in the radioimmunoassay of morphine-6-glucuronide
2 (M6G), N-(4-aminobutyl)normorphine-6-glucuronide 12 has been prepare
d, together with related haptens, using the imidate coupling method de
veloped for synthesis of M6G; a rebuttal of recent critical comments o
n our synthesis of M6G is included.
