Synthesis of side chain specifically deuterated (-)-Δ9-tetrahydrocannabinols
Nikas, Spyros P.,Thakur, Ganesh A.,Makriyannis, Alexandros
, p. 1065 - 1076 (2007/10/03)
(-)-Δ9-Tetrahydrocannabinols specifically deuterated at the n-pentyl side chain were prepared using the corresponding resorcinols as key intermediates. To obtain the deuterated resorcinols we developed conditions under which no deuterium scramb
