BioAssay: AID 128027

Compound was tested for analgesic activity by writhing assay in mouse after subcutaneous administration

Reaction of codeinone (2) with CH2N2 in the presence of Pd(OAc)2 yielded mixtures of starting material and (2) and 7 beta, 8 beta-methanodihydrocodeinone (3). Initial resolution of this mixture was achieved via carbonyl reduction followed by chromatography to give pure 7 beta, 8 beta-methanodihydrocodeine (4), which was oxidized to 3. Reaction of the mixture containing 2 and 3 with more ..

Description:
Title: Analgesic narcotic antagonists. 6. 7 beta, 8 beta-Methano- and 7 beta, 8 beta-epoxydihydrocodeinone.

Abstract: Reaction of codeinone (2) with CH2N2 in the presence of Pd(OAc)2 yielded mixtures of starting material and (2) and 7 beta, 8 beta-methanodihydrocodeinone (3). Initial resolution of this mixture was achieved via carbonyl reduction followed by chromatography to give pure 7 beta, 8 beta-methanodihydrocodeine (4), which was oxidized to 3. Reaction of the mixture containing 2 and 3 with mercaptoethanol and NaOH [2 leads to 8 beta-[(hydroxyethyl)thio]dihydrocodeinone (5)] allowed selective crystallization of 3. The beta configuration of the cyclopropane ring in 3 was established by cleavage with aqueous HCl to give the 8 beta-(chloromethyl) compound 6, followed by carbonyl reduction and dehalogenation to 8 beta-methyldihydrocodeine (8). Reaction of the N-(cycloalkylmethyl) derivatives (13 and 18) of 2 with CH2N2/Pd(OA)2 gave potential mixed agonist-antagonists and 14 and 19, which were purified by reduction-oxidation (14) or mercaptoethanol-base treatment (19). Compound 2, on oxidation with alkaline peroxide, gave the previously reported 7 beta, 8 beta-epoxydihydrocodeinone (22) as the hemimethanol ketal (21). Compound 3 was about ninefold more potent an agonist than dihydrocodeine, and the N-(cyclopropylmethyl)-7 beta, 8 beta-methano compound 19 had moderately potent mixed agonist-narcotic antagonist properties.
