A newreagent, N-methyl-2-dimethylaminoacetohydroxamic acid was developed for the selectivecleavage of active esters under neutral conditions. The kinetic studies and the applications of are described.
A compound of the formula:
1
in which R
1
and R
2
are each lower alkyl or combined together to form lower alkylene, R
3
is hydrogen or hydroxy, R
4
is hydrogen or acyl, and A is lower alkylene,
or a salt thereof, which is useful as a selective deacetylating agent.
