An Improved, Practical, and Scalable Five-Step Synthesis of Psilocybin
Kargbo, Robert B.,Meisenheimer, Poncho,Sherwood, Alexander M.,Tarpley, Gary
, p. 688 - 694 (2020/02/25)
Described herein is an improved synthesis of 3-[2-(dimethylamino)ethyl]-1 H -indol-4-yl dihydrogen phosphate (psilocybin). The protocol outlines: synthesis of multigram quantities of psilocybin, identification of critical in-process parameters, and isolation of psilocybin without the use of chromatography, TLC, or aqueous workup. The synthesis furnishes psilocybin in five steps in 23percent overall yield from an inexpensive acetoxyindole starting material. With specific focus on process control and impurity fate and removal, the improved procedure is amenable to providing high-quality psilocybin.
Observations concerning the synthesis of tryptamine homologues and branched tryptamine derivatives via the borrowing hydrogen process: Synthesis of psilocin, bufotenin, and serotonin

Observations concerning the synthesis of substituted tryptamine derivatives starting from indoles and 1,n-amino alcohols via the borrowing hydrogen process are discussed. This catalytic, single-step, and modular approach to tryptamines and homotryptamines allows the synthesis of branched and nonbranched tryptamines as well as tryptamine-based natural products such as psilocin, bufotenin, and serotonin.
Palladium-catalyzed synthesis of tryptamines and tryptamine homologues: synthesis of psilocin
Hu, Chunmei,Qin, Hua,Cui, Yuxin,Jia, Yanxing
experimental part, p. 9075 - 9080 (2010/01/16)
A new Pd-catalyzed method for the synthesis of tryptamines is developed, and its applications to the synthesis of Corey's aspidophytine tryptamine 15 and psilocin 20 are also described.
