S. Mahboobi et al., Synthesis of the racemates of the beta-carboline alkaloid chrysotricine and its diastereomer, MONATS CHEM, 131(4), 2000, pp. 383-392
The racemates of the rubiacea alkaloid Chrysotricine (1) and its diastereom
er are synthesized from the isomeric mixture of linalyl oxides 3 and trypta
mine in six steps, followed by separation of the diastereomers.
