Synthesis of (-)-Littoralisone
Chemexpress The loss of mental function associated with aging is thought to be due at least in part to the degradation of neurite connections between neurons. Natural products such as (-)-littoralisone…
The Stork Synthesis of (-)-Reserpine
The history of reserpine (3), isolated from the Indian shrub Rauwolfia serpentina, is storied. The anxiolytic activity of reserpine, the first tranquilizer, pointed the way to the development by Hoffmann-LaRoche…

Alkene metathesis in total synthesis: Valienamine, Agelastatin and Tonantzitlolone
Applications to natural product synthesis probe the limits of any synthetic method, as situations arise that would never have been considered in the course of first developing the method. PMID:35567400…
Best Synthetic Methods: Oxidation and Reduction
Although oxidation and reduction are common organic synthesis transformations, there is always room for improvement. The ideal reaction might use a solid, easily-measured reagent, a minimal amount of solvent, need…
Formation of Aromatic-Amino and Aromatic-Carbon Bonds
The formation of bonds to aromatic rings is the foundation of much of organic synthesis. There has been much excitement over the past several years around Pd- or Cu-mediated displacement…
Enantioselective Alkylation of the Indole Nucleus – Part One of Two:Enantioselective Organocatalytic Indole Alkylation
The indole nucleus, known as a privileged platform, is present in a wide range of natural products and important synthetic molecules. Price of 623583-09-5 Many strategies have been developed for…
Protection of N- and O-Functional Groups
O– and N-protection is often necessary in organic synthesis. Several recent advances in functional group protection-deprotection are particularly noteworthy. Formula of (S)-4-(1-Aminoethyl)phenol hydrobromide Primary benzenesulfonamides have been notoriously difficult to…
