LA-Azepane
LA-Azepane, or LSD-Azepane, also known as lysergic acid azepane or as lysergic acid hexamethylene imide, is a chemical compound of the lysergamide family related to lysergic acid diethylamide. It is an derivative of LSD in which the N,''N''-diethylamide moiety has been cyclized to form an azepane ring. The compound is very little studied and described itself, but is closely related to other amide-cyclized LSD analogues including LA-Pip, LSM-775, LPD-824, LPN, LSZ, and LA-Aziridine, among others. The chemical synthesis of the compound has been described. LA-Azepane was first described in the literature in a patent by Richard P. Pioch at Eli Lilly and Company in 1961. The patent had been filed 5years previously in 1956.
