Alkaloids 29-37 synemin Homo sapiens 137-140 30398210-1 2018 The proto-alkaloid synephrine {SYN; systematic name: 4-[1-hydroxy-2-(methylamino)ethyl]phenol}, C9H13NO2, is found to crystallize as a neutral molecule in the racemate and as a zwitterion in the pure enantiomer, in which the phenolic H atom has been transferred to the amino group. Alkaloids 10-18 synemin Homo sapiens 31-34 25790266-1 2015 The syn- and anti-diastereoisomeric forms of the reported structures of the marine alkaloids nakinadines D-F have been synthesized, for the first time in all cases, via an approach involving asymmetric Mannich-type (imino-aldol) reactions of methyl phenylacetate with N-tert-butylsulfinyl imines as the key steps to control the stereochemistry.
