In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis of 2-D-L-tryptophan by sequential Ir-catalyzed reactions, published in 2019-04-12, which mentions a compound: 7524-52-9, Name is H-Trp-OMe.HCl, Molecular C12H15ClN2O2, Safety of H-Trp-OMe.HCl.

Herein, we report a practical synthesis of 2-D-L-tryptophan via sequential Ir-catalyzed C-H borylation, and Ir-catalyzed C-2-deborylative deuteration steps. In this synthetic sequence, deprotection of the Boc (Boc = tert-butoxycarbonyl) and Me ester groups proved challenging, due to replacement of deuterium with hydrogen. However, mild deprotection conditions were developed to avoid this D/H scrambling. Further, 2-D-L-tryptophan is stable in many buffers used for biol. studies.

The above compounds were prepared by direct diazotization of Me anthranilate followed by addition of amino acid esters hydrochloride in a one-pot strategy. An equivocal synthesis of compound I (X = CH2; X1 = MeO) was achieved by alkylation of benzotriazin-4(3H)-one with Me chloroacetate.
