In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 126456-43-7, name is (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol, introducing its new discovery. name: (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol
Allyltrichlorostannane additions to alpha-amino aldehydes: Application to the total synthesis of the aspartyl protease inhibitors L-682,679, L-684,414, L-685,434, and L-685,458
The hydroxyethylene dipeptide isosteres L-682,679, L-684,414, L-685,434, and L-685,458 were synthesized in a few steps by a sequence involving an allyltrichlorostannane coupling with an alpha-amino aldehyde, followed by hydroboration of the corresponding 1,2-syn and 1,2-anti amino alcohols to give the diols, lactonization under TPAP conditions, lactone opening, and peptide coupling with the desired amine or dipeptide amide. The present synthetic approach represents a practical entry to a large range of other dipeptide isosteres.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 126456-43-7, and how the biochemistry of the body works.name: (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol
