Paragraph 0086; 0088; 0093, (2018/10/11)
The invention provides a preparation method of a chiral morpholine compound. With chiral ethylene oxide as a raw material, the preparation method comprises the steps of ring opening, cyclization and deprotection reaction to obtain the chiral 2-substituted morpholine compound. The preparation process is simple and environmentally friendly, has mild reaction conditions, is free of irritation or allergens, has higher total yield and good safety and is suitable for industrial amplification.

Compound formula I: wherein: X1 and X2 may be either (a) C and O, (b) N and N, or (c) C and NH, where the dotted bonds represents a double bond in the appropriate location; R1 and R2 are independently selected from hydrogen, an optionally substituted C1-7 alkyl group, an optionally substituted C3-20 heterocyclyl group, or an optionally substituted C5-20 aryl group, or may together form, along with the nitrogen atom to which they are attached, an optionally substituted heterocyclic ring having from 4 to 8 ring atoms; RN1 is selected from hydrogen and an optionally substituted C1-4 alkyl group; RC1 is selected from an optionally substituted C1-7 alkyl group, an optionally substituted C3-20 heterocyclyl group, or an optionally substituted C5-20 aryl group; or RN1 and RC1 may together form an optionally substituted C2-4 alkylene group.
