Lactams. XXII. Preparation of the Enantiomers of 6-Ethoxy-3-ethyl-2,3,4,5-tetrahydro-4-pyridineacetic Acid Ethyl Ester

The resolution of (+/-)-trans-1-benzyl-5-ethyl-2-oxo-4-piperidineacetic acid was effected with (R)-(+)=α-phenylethylamine through formation of the diastereomeric salts (+)-2 and (-)-3.Conversion of (+)-1 into the (3R,4R)-(+)-enantiomer of
