Acetol can be conveniently used as a reagent for the protection of carboxylic acids in peptide synthesis. It has been found to be inert and stable to hydrogenolytic and acidolytic conditions normally used in peptide synthesis. Deblocking has been selectively achieved undermildconditionsusing Bu4NF.3H2O in THF.

A series of N-protectedglycineactivatedesters was found to have antifertilityactivity in mice when administered intravaginally. The N-carbobenzoxyglycine vinyl ester and N-carbobenzoxyglycine 1,2-dibromoethyl ester analogs possessed the best activity in inhibiting pregnancy but were much less active when administered intraperitoneally. The acrosin enzymatic activity of sperm also was inhibited
