Disputed: Missing stereochemistry at one position

@Edgar181: I wonder if the position that's missing steterochemistry right now is a defined stereocenter at all? Aren't both possible forms in an equilibrium through opening and re-closing of the acetal? --Hbf878 (talk) 12:48, 25 October 2019 (UTC)

@Hbf878: In a C-glycoside such as this, ring opening and re-closing isn't possible because there is no acetal intermediate that can be formed. As far as I can tell, nothofagin was isolated as a single stereoisomer (as in File:Nothofagin structure.svg) and is defined as such. Ed (Edgar181) 13:00, 25 October 2019 (UTC)

I think my mind made up an extra 'O' somewhere... I added the stereochemical info that was missing. --Hbf878 (talk) 08:54, 28 October 2019 (UTC)
