Title: TBTU
Post by: Xera on November 03, 2022, 04:36:44 PM

Hey, I need help to understand TBTU as a coupling reagent. I am currently trying to draw it in Chemdraw but there seems to be two different ones?? I am not computing it and would love for someone to explain why there is this misunderstanding. I have linked the two different 'structures' would be amazing if anyone could enlighten me. Thanks a lot!
