"' Testosterone enanthate benziloylhydrazone "', also known as "'testosterone 17?-enanthate 3-benzilic acid hydrazone "', is a injected anabolic-androgenic steroid and an androgen ester specifically, the C17? enanthate ester and C3 benzilic acid hydrazone of testosterone which was never marketed.

Uncoupling proteins play a role in normal physiology, as in cold exposure or hibernation, because the energy is used to generate heat ( see thermogenesis ) instead of producing ATP . However, other substances, such as 2, 4-dinitrophenol and carbonyl cyanide m-chlorophenyl hydrazone, also serve the same uncoupling function, and are considered poisonous.

The first step is the deprotonation of the hydrazone of diazo compounds using CsF . At this point, the conjugate base could either decompose to give the diazo compound and undergo a [ 3 + 2 ] dipolar cycloaddition with the aryne to give the product, or a [ 3 + 2 ] annulation with aryne which would also give the final product.

The preparation of L-( " R " )-coniine by the reduction of ?-coniceine ( L-propenylpiperidine ) by L�ffler and Friedrich incorrectly, that pelletierine was the aldehyde ( ?-2-piperidyl-propaldehyde ) corresponding to coniine, and yielded " rac-" coniine when its hydrazone was heated with sodium ethoxide in ethanol at 156 170 �C . According to these authors, D-( " S " )-coniine is rendered almost optically inactive when heated with barium hydroxide and alcohol at 180 230 �C . Leithe has shown by observation of the optical rotation of ( + )-pipecolic acid ( piperidine-2-carboxylic acid ) and some of its derivatives under varying conditions, that it must belong to the D-series of amino acids.
