The preparation method of pyrrolidinium salt |
| abstract |
A two-step process for the preparation of compounds of formula I in salt or zwitterionic form, wherein R and R are each independently C 3 -C 8 -cycloalkyl or C 6 -C 10 -aryl; R 3 and R 4 are each independently is C 1 -C 8 -alkyl. This approach minimizes changes in the relative ratios of diastereoisomers. |
