A base-mediated procedure for the amidation of unactivated esters with aminoalcohols is reported. Optimization and exemplification of the catalytic process are described, furnishing products in 40–100% isolated yield.

Methods for modulating the levels of glucagon and blood glucose of a mammal are provided. In the subject methods, a positive allosteric modulator of AMPA/kainate receptors is administered to a host. The subject methods find use in applications where it is desired to increase one or both of the glucagon and blood glucose levels in a mammalian host. The subject methods find use in applications where it is desired to decrease the size, or breadth, of the circadian range of blood glucose levels in a mammalian host. The subject methods also find use in applications where it is desired to decrease the frequency, severity, or occurrence of hypoglycemia in a mammalian host. Finally, the subject method finds use in applications where it is desired to decrease the frequency, severity, or occurrence of nocturnal hypoglycemia in a mammalian host, particularly that which occurs in diabetics as a result of therapy with insulins or insulin analogs or other glucose lowering agents, or combinations of such agents.

An iminiumion triggered cascade reaction is described in the total synthesis of (+)-vincadifformine by the coupling of 3,3-substituted tetrahydropyridine and indole derivative. The strategy allows simultaneous construction of two new rings, three new sigma bonds, and two new stereogenic centers in one pot with complete stereochemical control.
