Nicolaou, K. C. et al. published their research in Angewandte Chemie, International Edition in 2008 | CAS: 18437-66-6

tert-Butyl (4-chlorophenyl)carbamate (cas: 18437-66-6) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.COA of Formula: C11H14ClNO2

An expedient strategy for the synthesis of tryptamines and other heterocycles was written by Nicolaou, K. C.;Krasovskiy, Arkady;Trepanier, Vincent E.;Chen, David Y.-K.. And the article was included in Angewandte Chemie, International Edition in 2008.COA of Formula: C11H14ClNO2 This article mentions the following:

N-Boc-protected anilines are converted into an array of useful N-heterocycles and tryptamines through an expedient, cascade-based synthetic sequence involving ortho metalation and subsequent coupling with N-Boc-pyrrolidin-3-one. In the experiment, the researchers used many compounds, for example, tert-Butyl (4-chlorophenyl)carbamate (cas: 18437-66-6COA of Formula: C11H14ClNO2).
