Application
The Pictet–Spengler reaction of D-Tryptophan methyl ester hydrochloride with piperonal in various solvents has been extensively studied, the solvent-dependence of stereoselectivities could be principally attributed to the solubility difference between cis and trans products 5-HCl in the used solvent, the best stereoselectivity (cis/trans = 99:1) was obtained using nitromethane or acetonitrile as the solvent. Cialis, 12a-epi-Cialis, deuterium-labeled, 3,3,12a-d3-Cialis, and 3,3,12a-d3-12a-epi-Cialis could be efficiently synthesized from D-Tryptophan methyl ester hydrochloride
