Diastereoselektive Hydroxyalkylierungen in 1-Stellung von Tetrahydroisochinolinen und Synthese von Aporphin-, Protoberberin- und Phthalid-Alkaloiden

Unsubstituted and 6,7-dialkyloxy-N-pivaloyl-tetrahydroisoquinolines 1-3 are converted to 1-bromomagnesium derivatives by sequential treatment with t-BuLi (-75 deg C/THF) and MgBr2*OEt2.Addition of the metalated tetrahydroisoquinolines to aliphatic or arom

SYNTHETIC PHOTOCHEMISTRY. SYNTHESIS OF (+/-)OLIVEROLINE AND (+/-)USHINSUNINE

Sodium borohydride reduction of 1-(2'-Bromobenzoyl)-2-methyl-3,4-dihydro-6,7-methylenedioxyisoquinolinium iodide (4) gave a mixture of alcohols which on irradiation in dil.HCl afforded (+/-) oliveroline and (+/-) ushinsunine.
