Abstract(R,S)-Atenolol was derivatized with Marfey’s reagent, (MR; 1-fluoro-2,4-dinitrophenyl-5-l-alanine amide or FDNP-l-Ala-NH2) and its four structural variants (FDNP-l-Phe-NH2, FDNP-l-Val-NH2, FDNP-l-Leu-NH2 and FDNP-l-Pro-NH2). MR reacts quantitatively with 1° and 2° amino groups and atenolol has a secondary amino group. The derivatization reactions were carried out under conventional and microwave heating and compared. The resulting diastereomers were separated on RP-TLC and on a C18… CONTINUE READING
