Morphine Alkaloids, CXVII: Investigation of the Azidolysis of Tertiary Alcohols of Thebaine Derivatives with Bridged Ring C

DOI:10.1002/ardp.19933260602
日期:——
Replacement of the C‐19 tertiary hydroxyl group of some thebaine and oripavine derivatives with bridged ring C (so‐called Bentley's compounds) for an azido group has been performed with hydrazoic acid. In case the hydroxyl group was connected to a centre of chirality, substitution resulted in the formation of diastereomeric mixture of azides and elimination took place as well, the extent of which was
