We report the first examples of hydrogen-bond-promoted acceleration of hetero-Diels-Alder reactions and the use of such catalysis for the hetero-Diels-Alder reactions of simple, unactivated ketones. Several spiro-fused dihydropyans were synthesized in good yields using this procedure. This activation protocol represents
Biheteroaromatic diphosphine oxides-catalyzed stereoselective direct aldol reactions.

Synthetic and natural peptides that act as nonselective melanocortin receptor agonists have been found to be anorexigenic and to stimulate erectile activity. We report the design and development of 1, a potent, selective (1184-fold vs MC3R, 350-fold vs MC5R), small-molecule
Knoevenagel Condensation is an organic reaction named after Emil Knoevenagel. It is a classic C-C bond formation reaction and a modification of the Aldol Condensation.
