An arylcyclohexylamine is composed of a cyclohexylamine unit with an aryl moiety attachment. The aryl group is positioned geminal to the amine. In the simplest cases, the aryl moiety is typically a phenyl ring, sometimes with additional substitution. The amine is usually not primary; secondary amines such as methylamine or ethylamine, or ...
Phencyclidine or phenylcyclohexyl piperidine ( PCP ), also known in its use as a street drug as angel dust among other names, is a dissociative anesthetic mainly used recreationally for its significant mind-altering effects. [1] [5] PCP may cause hallucinations, distorted perceptions of sounds, and violent behavior.
Cyclohexylamine is used as an intermediate in synthesis of other organic compounds. It is the precursor to sulfenamide -based reagents used as accelerators for vulcanization. The amine itself is an effective corrosion inhibitor. It has been used as a flushing aid in the printing ink industry. [5]
Borsche–Drechsel cyclization is the central step in Borsche–Drechsel carbazole synthesis, where in the first step phenylhydrazine is condensed with cyclohexanone to form the cyclohexanone phenylhydrazone, and in the final step the resulting tetrahydrocarbazole is oxidized to carbazole itself.
The Erlenmeyer–Plöchl azlactone and amino acid synthesis, named after Friedrich Gustav Carl Emil Erlenmeyer who partly discovered the reaction, is a series of chemical reactions which transform an N-acyl glycine to various other amino acids via an oxazolone (also known as an azlactone). Azlactone chemistry: step 2 is a Perkin variation
mechanism. In organic chemistry, the Ei mechanism ( Elimination Internal/Intramolecular ), also known as a thermal syn elimination or a pericyclic syn elimination, is a special type of elimination reaction in which two vicinal (adjacent) substituents on an alkane framework leave simultaneously via a cyclic transition state to form an alkene in ...
Longest linear sequence. In synthetic chemistry, the longest linear sequence, commonly abbreviated as LLS, is the largest number of reactions required to go from the starting materials to the products in a multistep sequence. [1]
The replication fork is a structure that forms within the long helical DNA during DNA replication. It is produced by enzymes called helicases that break the hydrogen bonds that hold the DNA strands together in a helix. The resulting structure has two branching "prongs", each one made up of a single strand of DNA.
