测定了四对新合成的四氢β-咔啉化合物的~13C NMR谱,通过APT,HETCOR和HETCOLOC谱指认了所有碳的归属.所确定的化学位移规律可以用来确定它们的构型.
The ~ 13C NMR spectra of four newly synthesized tetrahydro-β-carbolines were determined and assigned to all carbons by the APT, HETCOR, and HETCOLOC spectra.The determined chemical shifts can be used to determine their configuration.
