Phenylpropionate ester

The 3-phenylpropionate ester has been used in nucleoside synthesis. It is cleaved by a-chymotrypsin (37°, 8-16 h, 70-90% yield). It can be cleaved in the presence of an acetate. ... 

H- 1,3-Oxazines are formed by the self-condensation of 2-bromo-2,3-dicyanopropionate or 2-cyano-3-phenylpropionate esters in the presence of phosphites (Scheme 56) <75CR(C)(281)51). 

Bemis et al. (1992) investigated the difference of 60-fold between the hydrolysis of two acyl-chymotrypsin derivatives, following the reaction with enantiomeric lactones that leads to P-substituted p-phenylpropionic esters. The S-ester (kdifferent molecules are modeled. 

Also referred to as Propionic Acid Phenyl Ester. Phenylpropionate will extend the release of active steroid a few days longer than propionate. To keep blood levels even, injections are given at least twice weekly. Durabolin is the drug most commonly seen with a phenylpropionate ester (nandrolone phenylpropionate), although it is also used with testosterone in Sustanon and Omnadren.
