Synthesis and properties of enantiopure bicyclic amidines
摘要:
The enantiopure bicyclic amidine bases 5a-c were synthesized from alcohol 8, via alkylation of the appropriate nitriles. The phenylsulphonylamidine 5a was subjected to X-ray crystallography as its nitrate salt, and was shown by H-1 NMR to differentiate analytically between the enantiomers of chiral carboxylic acids.
