Concise synthesis of N3- and N6-monoprotected
3,6-diazabicyclo[3.1.1]heptanes
3,6-diazabicyclo[3.1.1]heptanes
Bridged bicyclic piperazines are important building blocks in medicinal chemistry research. The bicyclic
piperazine 3,6-diazabicylo[3.1.1]heptane is of particular interest as a piperazine isostere because it is
achiral and shows similar lipophilicity to that of piperazine based on the cLogP of a derived analog.
Practical Synthesis of 3-Oxa-6-azabicyclo[3.1.1]heptane Hydrotosylate
Bridged bicyclic morpholines are important building blocks in medicinal chemistry research. The bicyclic morpholine 3-oxa-6-azabicylo[3.1.1]heptane (3a) is of particular interest as a morpholine isostere because it is achiral and shows similar lipophilicity to that of morpholine, based on the cLogP of a derived analogue. The first synthesis of morpholine 3a (tosylate salt) is described; the seven-step sequence begins with inexpensive starting materials and uses straightforward chemistry.Read more TPGS-750-M: A Second-Generation Amphiphile for Metal-Catalyzed
Cross-Couplings in Water at Room Temperature
Cross-Couplings in Water at Room Temperature
An environmentally benign surfactant (TPGS-750-M), a diester composed of racemic R-tocopherol, MPEG-750, and succinic acid, has been designed and readily prepared as an effective nanomicelle-forming species for general use inmetal-catalyzed cross-coupling reactions in water. Several“name” reactions, including Heck, Suzuki-Miyaura, Sonogashira, and Negishi-like couplings, have been studied using this technology, as have aminations, C-H activations, and olefin metathesis reactions.
