-
Page/Page column 29; 30; 34, (2019/05/10)
The invention provides methods and compositions relating to an ultrapure formulation of 5-(1,1-dimethylheptyl)-resorcinol (ultrapure DMHR). The invention features methods for making ultrapure DMHR, including methods that minimize the production of unwanted side products (e.g., the production of homologous alkyl-chain impurities). The invention also features methods of making cannabinoids, such as (6aR,10aR)-1-hydroxy-6,6-dimethyl-3-(2-methyl-2-octanyl)-6a,7,10,10a-tetrahydro-6H-benzo[c]chromene-9-carboxylic acid (ajulemic acid), using ultrapure DMHR, including methods that minimize the production of unwanted side products (e.g., the production of homologous alkyl-chain impurities) in the resulting cannabinoid preparation.

(Chemical Equation Presented) A stereocontrolled synthesis of (-)-CP55,940, a potent cannabinoid receptor agonist, has been attained using a novel aldolization/retroaldolization interconversion strategy, in which a temporarily generated chiral aldol motif plays essential roles.
High enantiomeric purity dexanabinol for pharmaceutical compositions
-
Page/Page column 11, (2010/02/07)
The present invention relates to a synthetic cannabinoid, dexanabinol, of enantiomeric purity in excess of 99.90%, or to a pharmaceutically acceptable salt, ester or solvate of said compound. The present invention also relates to pharmaceutical grade compositions comprising said compound of high enantiomeric purity, and uses thereof for prevention and treatment of neurological disorders, chronic degenerative diseases, CNS poisoning, cognitive impairment, inflammatory diseases or disorders, autoimmune diseases or disorders, pain, emesis, glaucoma and wasting syndromes.

, p. 6576 - 6582 (2007/10/03)
An effective synthesis of tricyclic, nonclassical cannabinoids has been developed on the basis of a cation-olefin cyclization that forms the two nonaromatic rings with the desired stereochemistry in a single step.
5-(Tertiary alkyl) resorcinol preparation and intermediates therefor
-
, (2008/06/13)
2,6-Dimethoxyphenol reacts with a tertiary carbinol in the presence of an acid to provide exclusively a 1-hydroxy-2,6-dimethoxy-4-tertiary alkyl)benzene, which when reacted with a halogenated disubstituted phosphite affords a 2,6-dimethoxy-4-tertiary alkyl)phenyl disubstituted phosphate. Reduction of the phenyl phosphate derivative by reaction with an alkali metal affords a 1-(tertiary alkyl)-3,5-dimethoxybenzene, which upon reaction with a demethylating agent provides a 5-(tertiary alkyl)resorcinol.
Cannabinoids. 1. 1 Amino and 1 mercapto 7,8,9,10 tetrahydro 6H dibenzo[b,d]pyrans
Matsumoto,Stark,Meister
, p. 17 - 24 (2007/10/09)
A series of 1 amino and 1 mercapto 7,8,9,10 tetrahydro 6H dibenzo [b,d] pyrans was synthesized and subsequently evaluated in three rodent test systems for CNS activity. The structure activity data generated indicate that, in general, a change of the 1 hydroxy group to an amine results in a retention of pharmacological activity but that a change to sulfur results in loss of pharmacological activity. Derivatization of the 1 amino group with various functions decreased the activity of the parent compound. For optimum potency, in all series, the 3 position alkyl side chain should be either 1,1 or 1,2 dimethylheptyl. With either the 1 hydroxy or 1 amino 7,8,9,10 tetrahydro 3 (1,1 dimethylheptyl) 6,6,9 trimethyl 6H dibenzo [b,d]pyran (4c or 10c), preparation of the optically active antipodes did not lead to any great degree of separation of activity. Both of the antipodes possess pharmacological activity as measured in these rodent test systems.
