Stereoinduction
網頁Extensive and interactive screening of the precursor, catalyst, base, stirring and temperature was required to achieve high stereoinduction. The result is an efficient 5-step radiolabeling method to reliably synthesize l- or d-[11C]phenylalanine with an excellent enantiomeric excess of >90% and almost quantitative radiochemical conversion of >95% (n > 5). 網頁6 小時前 · The same shoe, in men’s sizing. $150 from Amazon. $112 from Zappos. $112 from Hoka One One.
