Summary: |
The titanium derivative 2 of the bislactim ether 1 of cyclo(-LVal-Gly-) reacts with aldehydes and ketones 3 highly diastereoselectively to give the syn-addition products 4. Upon hydrolysis with diluted trifluoroacetic acid the compounds 4 yield besides methyl L-valinate the (2R,BS)-threo-serinme ethyl esters 5.
