Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Potassiumtris(1-pyrazolyl)borohydride, is researched, Molecular C9H10BKN6, CAS is 18583-60-3, about Enantiocontrolled Synthesis of 2,3,6-Trisubstituted Piperidines Using (η3-Dihydropyridinyl)molybdenum Complexes as Chiral Scaffolds. Total Synthesis of (-)-Indolizidine 209B.Safety of Potassiumtris(1-pyrazolyl)borohydride.
Enantiopure TpMo(CO)2(pyridinyl) complexes were prepared using an efficient and scalable enzymic kinetic resolution of the precursor to the molybdenum complex. A single TpMo(CO)2(pyridinyl) complex can function as a chiral scaffold for the enantiocontrolled synthesis of either 2,3,6-cis- or 2,6-cis-3-trans-trisubstituted piperidines. The synthetic potential of this methodol. was demonstrated by a total synthesis of (-)-indolizidine 209B.
