Talk:Tortuosamine

Stereochemistry question
Chemical Abstracts has the following listings for the stereoisomers of tortuosamine:
 * 35722-04-4: (R)-(-)-tortuosamine
 * 51934-13-5: (S)-(+)-tortuosamine
 * 79517-20-7: (±)-tortuosamine

This is inconsistent with Pubchem which lists (-)-tortuosamine as the (S)-isomer. I don't know which is correct. -- Ed (Edgar181) 20:28, 25 October 2019 (UTC)
