The invention provides chiral morpholine compounds. The structural general formula of the chiral morpholine compounds is as shown in the description. The invention further comprises a preparation method of the chiral morpholine compounds. The chiral morpholine compounds are prepared by using benzoin as a starting material, performing reductive amination, and performing chemical resolution on enantiomers and acid-catalyzed ester condensation reaction. The invention further provides amino acid compounds prepared from the chiral morpholine compounds, and a preparation method and application of the amino acid compounds.

A convenient synthesis of optically pure 4-Boc-5,6-diphenylmorpholin-2-one and 4-Cbz-5,6-diphenylmorpholin-2-one by reaction of (+)- or (-)-2-amino-1,2-diphenylethanol with ethyl bromoacetate, followed by N-protection, and p-TsOH-mediated ring-closure is
Optically active carboalkylated amino alcohols and their utilization in optical resolution
-
, (2008/06/13)
A carboalkylated amino alcohol having each of the below shown formulae is novel and optically active. A separating agent comprising the alcohol and a support is effectively useful to separate a variety of racemates for example with chromatography. The alc
