Point-to-helical chirality transfer for a scalable and resolution-free synthesis of a helicenoidal DMAP organocatalyst.
نویسندگان
چکیده
The synthesis of a second-generation [6]-helicenoidal DMAP organocatalyst is reported. The synthesis is reliant upon a highly diastereoselective Rh-catalysed [2 + 2 + 2] triyne cycloisomerization, using an existing stereocentre to control the sense of forming helicity. Taken together, a scalable (>1 g), resolution-free entry to a helical DMAP with the capacity for subsequent functionalization, has been achieved.

P-97: Optimized Combined Electrical-Chemical Parthenogenetic Activation for Zona Free Sheep Oocyte
Background: Artificial oocyte activation (AOA) has important implications in assisted reproductive technique (ART) with particular importance in somatic cell nuclear transfer (SCNT). Parthenogenesis activation using zona- free oocytes offers an alternative model that could be applied to develop protocols for the activation of reconstructed embryos for cloning. Materials and Methods: To establis...

In this research, (Carboxy-3-oxopropylamino)-3-propylsilylcellulose (COPAPSC) as an organocatalyst, has been synthesized by grafting of succinic anhydride on the NH2-modified cellulose (cellulose functionalized with 3- aminopropyltriethoxysilane). The –CO2H group-functionalized cellulose (COPAPSC) is used as a catalyst for the synthesis of coumarin derivatives from the reaction of phenolic subs...

An organosuperbase (N,N-dimethylbiguanide) immobilized on mesoporous and magnetically separable silica supports, was found for the first time, to act as a highly-stable, scalable and efficient heterogeneous catalyst for the Henry reaction under mild and neutral condition. Several factors such as catalyst amount, solvent and reaction time concerning the reactivity were also discussed. The proced...
