Synthesis of 3-halomethyl-2,3,4,5-tetrahydro-2,5-methano-1H-2-benzazepines and their rearrangement to 4-halo-1,2,3,4,5,6-hexahydro-2,6-methano-2-benzazocines
Abstract
This study reports a three-step synthesis of 3-halomethyl-2,3,4,5-tetrahydro-2,5-methano-1 H-2-benzazepines 2a–c and the rearrangement of 2a–b to 4-iodo- and 4-bromo-1,2,3,4,5,6-hexahydro-2,6-methano-2-methano-2-benzazocines 1a–b.
