Morpholinium acetate

This reaction is generally catalyzed by weak bases, such as tetrabutylammonium hydroxide,potassium phosphate, morpholinium acetate,K2COs, NH4Ac, ethylenediammonium diacetate, piperidine, 2s,4h,4j diethylamine, j zinc... 

On the other hand, the use of morpholinium acetate suggests Knoevenagel reaction conditions, with enamine intermediacy. The mechanism would change begging in the second step as follows ... 

Preparative, paper-chromatography is frequently used for further fractionation of the resulting mixtures. The high lability of glycosyl esters of nucleoside pyrophosphates seriously limits the choice of solvent systems. Systems used most commonly are neutral or slighdy acidic mixtures of ethanol with ammonium acetate,24,25 or weakly acidic solvents based on 2-methylpropionic acid.26 A solvent system containing morpholinium borate has also been found extremely useful.27... 

However, both amino groups of A,A-acetals may be replaced in other cases morpholinium dimorpholinoacetate and anisole give di-(p-methoxyphenyl)-acetic acid in 74% yield 821... 

DMTMM 138 decomposes completely within 3 h at room temperature if suspended in CH2CI2, by demethylation at the morpholinium nitrogen (Equation 55). The compound is stable in diethyl ether, ethyl acetate, or tetrahydro-furan (THF), but decomposes slowly in DMSO or MeCN. Moreover, neither demethylation nor solvolysis occurred when DMTMM was dissolved in water or MeOH thus, reaction can be conducted in nonanhydrous solvents. No allergic properties of DMTMM were observed <1999T13159>.
