Polymorphic Packing Arrangements in a Class of Engineered Organic Crystals
Polymorphism occurs in the family of engineered cocrystals that form from N,N ‘-bis(p-X-phenyl)melamines (X = H, F, Cl, Br, I, CH3, and CF3) and barbital. X-ray powder... -
Novel Amphiphilic Conetworks Composed of Telechelic Poly(ethylene oxide) and ...
Amphiphilic conetworks (APCNs) containing covalently bonded hydrophilic poly(ethyleneoxide) (PEO) and hydrophobic polyisobutylene (PIB) have been synthesized by chain end... -
Dendrimer-Supported Oligothiophene Synthesis: Aliphatic Ether Dendrimers in ...
The first dendrimer-supported synthesis of oligothiophenes is reported. The dendrimer serves both as a solubilizing group and a “handle” to facilitate the iterative synthesis of... -
Total Synthesis of the Ristocetin Aglycon
The first total synthesis of the ristocetin aglycon is described employing a modular and highly convergent strategy. An effective 12-step (12% overall) synthesis of the ABCD... -
