biosynthesis, were investigated. Starting from β-phenylethylamines the corresponding 3-chloro- N -phenethylpropionamides were prepared and transformed into N -phenethyl-3-phthalimidopropionamides. These amides were cyclized via Bischler-Napieralski reaction to yield after hydrolytic deprotection 1-(aminoethyl)tetrahydroisoquinolines. The 1,6,7,11b-tetrahydro-2 H -pyrimido[4,3- a ]isoquinoline ring system
