Ball milling of aromatic, heteroaromatic, vinylic, and aliphatic esters with ethanol and calcium nitride afforded the corresponding primary amides in a transformation that was compatible with a variety of functional groups and maintained the integrity of a stereocenter α to carbonyl. This methodology was applied to α-amino esters and N-BOC dipeptide esters and also to the synthesis of rufinamide, an antiepileptic drug.

(Chemical Equation Presented) The use of magnesium nitride (Mg 3N2) as a convenient source of ammonia has been explored for the direct transformation of esters to primary amides. Methyl, ethyl, isopropyl, and tert-butyl esters are converted to the corresponding carboxamides in good yields (75-99%).
Therapeutic morpholino-substituted compounds

Morpholino-substituted pyridopyrimidine, quinolone, and benzopyranone derivatives inhibit phosphoinositide (PI) 3-kinase, an enzyme that regulates platelet-adhesion processes. As a consequence, the compounds in question have anti-thrombotic activity, as well as other pharmaceutical properties. The compounds claimed are represented by formula (I), (II) and (III). PI 3-kinase generates 3-phosphorylated PI second messengers which stimulate platelet adhesion under blood-flow conditions. Because platelet adhesion is a necessary step in the formation of a thrombus, inhibition by these compounds of PI 3-kinase under such conditions inhibits or prevents thrombus formation. The compounds are useful in treating PI 3-kinase-dependent conditions including cardiovascular diseases such as coronary artery occlusion, stroke, acute coronary syndrome, acute myocardial infarction, vascular restenosis, atherosclerosis, and unstable angina; respiratory diseases such as asthma, chronic obstructive pulmonary diseases (COPD), and bronchitis; inflammatory disorders; neoplasms including cancers such as glioma, prostate cancer, small cell lung cancer, and breast cancer, and diseases linked to disordered white blood cell function, such as autoimmune and inflammatory diseases.
