Chemistry, like all the natural sciences, begins with the direct observation of nature— in this case, of matter.102195-79-9, Name is (2S,4S)-1-tert-Butyl 2-methyl 4-hydroxypyrrolidine-1,2-dicarboxylate, SMILES is O=C(N1[C@H](C(OC)=O)C[C@H](O)C1)OC(C)(C)C, belongs to amides-buliding-blocks compound. In a document, author is Xiao, Yelan, introduce the new discover, Category: amides-buliding-blocks.
An efficient asymmetric cascade reaction of keto esters with alkynyl alcohols and amides was catalyzed by the combination of achiral gold(I) catalysis and chiral Rh(III) Lewis acid catalysis as asymmetric relay catalysis. The corresponding spiroketals and spiroaminals were synthesized in good yields (up to 99%), with good diastereoselectivity (up to 20:1 dr) and excellent enantioselectivity (up to 98% ee).
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 102195-79-9 is helpful to your research. Category: amides-buliding-blocks.
