ADVANCES IN CARBOHYDRATE CHEMISTRY
Elimination of methoxyl is possible in only two ways, as CH30- or CHjOH, but
acetoxyl is eliminated in four ways, as CHsCO^H, CHSCOO, CHjCO-, or CH8==C
==O. The last is most characteristic of the unsaturated species formed by the ...

Two one-proton singlets at 8 5.23 and 6.18 could be assigned as protons
geminal to hydroxyl and acetoxyl groups, respectively. The position of the acetyl

Stereoselective Synthesis (Part K)
The 1H-NMR spectrum (CDCl3) showed a signal at 8 5.57 (1H, d, J=8 Hz) due to
the C-5 proton, indicating the insertion of an acetoxyl group at one of the benzylic
positions. It was shown that acetoxylation in compound (88) could be selective ...

Strategies for Organic Drug Synthesis and Design
Treatment of that product with the azetidone (16-3) leads to the replacement of
the acetoxyl next to nitrogen, in this case with retention of the configuration (16-4)
. This result can be rationalized by assuming an initial loss of the acetoxyl to form
