Can only refluxing of L- 4 -hydroxyphenylglycine MIBK convert it mixture of DL?
this is bad idea in case 4 Hydroxyphenylglycine (by refluxing you can be obtaine polimer). y can try refl it under argon atm 48-70h but chance is low.
more better do it yourself by Streker from 4 Hydroxyphenylaldehyde and KCN.
Hello all, I wanted to know, can I use galaxy (USA, Europe or Australia) platform for analyzing the shotgun data, and can it be used for publication purpose as well? Thanks :)
