-
Paragraph 0058; 0060; 0067, (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.

Efficient syntheses of chiral fragments derived from chiral amino alcohols are described. Several unique scaffolds were readily accessed in 1-5 synthetic steps leading to 45 chiral fragments, including oxazolidinones, morpholinones, lactams, and sultams. These fragments have molecular weights ranging from 100 to 255 Da and are soluble in water (0.085 to >15 mM).

Four new copper(II)/diamine complexes comprising some (+)-sparteine surrogates and a cyclohexane-derived diamine were prepared and evaluated as chiral catalysts in desymmetrisation of meso-diols and asymmetric Henry reactions. Mono-benzoylation reactions generated two products with high enantioselectivity (90:10 to 97:3 er). Asymmetric Henry reactions gave nitro alcohols in 90:10 to 98:2 er. Notably, the sense of induction with the (+)-sparteine surrogates was opposite to that obtained using the copper(II)/(?)-sparteine complex. One of the nitro alcohol products was utilised in a concise synthesis of a chiral morpholine.

We studied methods of stereospecific synthesis that enabled us to obtain variously substituted morpholinic compounds and to determine their absolute configuration.From a study of the chiroptical properties of synthetic N-(2-pyridyl-N-oxide) derivatives of optically active morpholines, it was possible to correlate the sign of the Cotton effect with the absolute configuration.This correlation agrees with that previously established for derivatives of the piperidine type.By evaluating the various contributions to the Cotton effect of substituents in positions 2 and 3, we established the absolute configuration of bicyclic compounds condensed in the two positions mentioned above.
