Aziridine carbamate linked cannabinoid conjugate components are synthesized as follows. A cannabinoid (CBD in this example) is reacted with phosgene (or a suitable phosgene surrogate) and an aminoaziridine ([88714-40-3] in this example) under standard basic conditions to form the desired carbamate linked product.

Aziridine carbonate linked cannabinoid conjugate components are synthesized as follows. A cannabinoid (CBD in this example) is reacted with phosgene (or a suitable phosgene surrogate) and a hydroxyaziridine ([25662-15-1] in this example) under standard basic conditions to form the desired carbonate linked product.

Aziridine ester linked cannabinoid conjugate components are synthesized as follows. The previously reported hydroxymethyl building block [126587-35-7] is treated with base, in this example sodium hydride, to generate the aziridinyl intermediate. Removal of the BOC protecting group followed by alkylation of the resulting amine gives the alkyl aziridine-ester intermediate. Standard hydrolysis of the ester gives the carboxylic acid precursor, which is esterified with the cannabinoid under standard esterification conditions to give the desired product.

Aziridine imidate linked cannabinoid conjugate components are synthesized as follows. A cannabinoid (CBD in this example) is reacted with an imidocarbonyl chloride (in this case [5652-90-4]) and a hydroxyaziridine ([25662-15-1] in this example) under standard basic conditions to form the desired imidate linked product.

Aziridine isourea linked cannabinoid conjugate components are synthesized as follows. A cannabinoid (CBD in this example) is reacted with an imidocarbonyl chloride (in this case [5652-90-4]) and an aminoaziridine ([88714-40-3] in this example) under standard basic conditions to form the desired isourea linked product.

Aziridine phosphorodiamide linked cannabinoid conjugate components are synthesized as follows. Using conditions similar to those referenced in the Scheme, N,N-Dimethylphosphoramidodichloridate ([677-43-0]) is reacted with an aminoaziridine ([88714-40-3] in this example). The adduct is then reacted with a cannabinoid (CBD in this example) under standard basic conditions to form the desired product.

Aziridine thiocarbamate linked cannabinoid conjugate components are synthesized as follows. A cannabinoid (CBD in this example) is reacted with thiophosgene (or a suitable thiophosgene surrogate) and an aminoaziridine ([88714-40-3] in this example) under standard basic conditions to form the desired thiocarbamate linked product.

Aziridine thiocarbonate linked cannabinoid conjugate components are synthesized as follows. A cannabinoid (CBD in this example) is reacted with thiophosgene (or a suitable thiophosgene surrogate) and a hydroxyaziridine ([25662-15-1] in this example) under standard basic conditions to form the desired thiocarbonate linked product.

[Figure (not displayed)]

Aziridine thiophosphinodiamide linked cannabinoid conjugate components are synthesized as follows. Using conditions similar to those referenced in the Scheme, dimethylphosphoramidothioic dichloride ([1498-65-3]) is reacted with an aminoaziridine ([88714-40-3] in this example). The adduct is then reacted with a cannabinoid (CBD in this example) under standard basic conditions, to form the desired product.
