2,3-Dimethyl-1,4-naphthoquinone derivatives as bioreductive alkylating agents with cross-linking potential
Abstract:
Bioreducible 2,3-disubstituted 1,4-naphthoquinones have been synthesized and evaluated for anticancer activity by measuring their capacity to prolong the life span of Sarcoma 180 tumor bearing mice. The leaving group in the 2- and 3-positions of these agents significantly influenced the degree of antineoplastic activity, with the most active agents being the methyl sulfonate (5), the methyl carbamate (9), and the 2-chloroethyl carbamate (10) derivatives; when these quinones were administered daily for 6 consecutive days, they produced maximum T/C X 100 values of 232, 266, and 230, respectively.

Preparation of Alkynes: Alkylation Reaction
Alkylation of terminal alkynes with primary alkyl halides in the presence of a strong base like sodium amide is one of the common methods for the synthesis of longer carbon-chain alkynes. For example, treatment of 1-propyne with sodium amide followed by reaction with ethyl bromide yields 2-pentyne.
Preparation of Alkynes: Dehydrohalogenation
Alkynes can be prepared by dehydrohalogenation of vicinal or geminal dihalides in the presence of a strong base like sodium amide in liquid ammonia. The reaction proceeds with the loss of two equivalents of hydrogen halide (HX) via two successive E2 elimination reactions.
Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
