Optical rotatory dispersion and absolute configuration—X α- and β-phenylethylamine S

Abstract ORD and CD measurements on α- and β-phenylethylamines and a cyclic analogue possessing the benzoquinolizidine structure indicate that the absolute configuration of the asymmetric center may be assigned from the ORD curve. Compounds of S-configuration exhibit a positive multiple Cotton effect between 270 and 250 mμ.

Optical rotatory dispersion and absolute configuration—XII : The argemonine alkaloids☆

Abstract ORD and CD measurements have been carried out on the alkaloids of the argemonine series, and have been related to the UV absorption and absolute configuration of these compounds. Of the 6 known argemonine alkaloids, five are configurationally identical.
