Progress in Heterocyclic Chemistry
... substrate (giving 4, X = CONH2), and the amidase then performs a kinetic
resolution on the amide, producing the unstable acid 5 and the desired chiral
amide < 03JOC4570>. Lipase mediated acetylative resolution of racemic
epoxides, ...

Carbohydrates: Structures, Syntheses and Dynamics
Conditions have been found under which acid-catalysed acetylative
desulphation of agarobiitols and carrabiitols is effected without concomitant
glycosidic bond cleavage (Falshaw and Furneaux. I995b). Hydrogen chloride in
anhydrous ...

Handbook of Porphyrin Science: Synthesis and structural studies
In this case the aromatization is effectively applied to the enolic form, giving after
acetylative quenching an acetoxysubstituted monobenzoporphyrin (Scheme 14).
Mild conditions account for the clean transformations without undesirable ...

... by subsequent reprotection and hydrolysis of the vinylic chloride to afford the
diketone intermediate 26, which underwent cyclization and acetylative
isomerization to afford 18,18,18-trifluorosteroid 27 in 24% yield over the five-step
sequence.

General Synthetic Methods
Acetylative cleavages of (arylsulphonyl )ureas afforded iso- 536 cyanates in
addition to N-acety larenesulphonamides . Methylthiomethyl- , phenylthiomethyl-
and bis(phenylthio)methyl- isocyanates were prepared from the corresponding ...

122-124 Other iV-desulfation techniques include reacting sodium heparinate in
either 11% acetic acid at 68°C or via acetylative desulfation with acetic anhydride
in concentrated sulfuric acid.125' 126 The methods however are not completely ...

The acetylative ring closure of 5,6-diaminoquinoxaline (5.280; R=H) [generated
in situ by reduction of 5,6-dinitroquinoxaline (5.279)] affords the anticipated fused
benzimidazole (5.281), a derivative of the rare imidazo[4,5-f]quinoxaline ring ...

Comprehensive Organic Functional Group Transformations: ...
A^-alkylidene-bis-amides have also been prepared by the acetylative hydrolysis
of the Af-[a-(benzylideneamino)benzyl]benzamides (82) <64JA1701>. These
methods, however, require the prior formation of the aminal skeleton and
therefore ...

This technique of acetylative de-esterification has also been applied to the
mucilage of Dilsea edulis (Dillon & McKenna 1950) and now in the present
instance to the Furcellaria mucilage. One feature of this method is that the
sulphur-free ...
