Synthesis of (±)-acetylnorloline via stereoselective tethered aminohydroxylation
Hovey, M. Todd,Eklund, Emily J.,Pike, Robert D.,Mainkar, Anshul A.,Scheerer, Jonathan R.

Loline alkaloids exhibit a strained ether-bridged pyrrolizidine skeleton and possess insecticidal and insect antifeedant properties. The synthesis of acetylnorloline, a prototypical member of the alkaloid family, is described. Central to the route is a st
Improved biomimetic total synthesis of D,L-stephacidin A
Greshock, Thomas J.,Williams, Robert M.

The direct conversion of β-hydroxyproline derivatives into 5-hydroxypyrazin-2(1H)-ones under Mitsunobu conditions has been discovered to be a general biomimetic protocol generating IMDA intermediates and has been applied to the concise, biomimetic total syntheses of D,Lstephacldin A and D,L-brevianamide B.
Synthesis of models of the BC ring systems of MPC1001 and MPC1001F

Piperazinedione 13, representing the BC rings of the anti-prostate cancer fungal metabolite MPC1001, was prepared by a route in which a sulfur-stabilized carbanion derived from 22 cyclizes onto the terminal ester of the pendant chain attached to N1. Another model, 14, was synthesized by cyclization of an α-ketoamide nitrogen onto an ester; 14 represents the BC rings of MPC1001F.
Design and synthesis of 3-arylpyrrolidine-2-carboxamide derivatives as melanocortin-4 receptor ligands
Tran, Joe A.,Tucci, Fabio C.,Arellano, Melissa,Jiang, Wanlong,Chen, Caroline W.,Marinkovic, Dragan,Fleck, Beth A.,Wen, Jenny,Foster, Alan C.,Chen, Chen

Based on 3-phenylpropionamides, a series of 3-arylpyrrolidine-2-carboxamide derivatives was designed and synthesized to study the effect of cyclizations as melanocortin-4 receptor ligands. It was found that the 2R,3R-pyrrolidine isomer possessed the most
