Synthetic Photochemistry: Synthesis of (+/-)-Oliveridine

The first synthesis of (+/-)-oliveridine (9b) and (+/-)-epioliveridine (9a) are described.The key steps are:(i) preparation of N--2'-bromo-5'-methoxyphenylacetamide (4), its Bischler-Napieralski cyclisation followed by m

Photocyclisation of 1-(2'-Halo-α-hydroxybenzyl)-1,2,3,4-tetrahydroisoquinolines; Synthesis of (+/-)-Oliveridine

In contrast to α-deoxy analogs, photocyclisation of 1-(2'-halo-α-hydroxybenzyl)-1,2,3,4-tetrahydroisoquinolines to aporphines succeeds even in cyclohexane solvent, probably because of internal hydrogen bonding.A synthesis of the alkaloid oliveridine is de
