Component match in rhodium catalyzed three-component reactions of ethyl diazoacetate, H2O and aryl imines: a highly diastereoselective one-step synthesis of beta-aryl isoserine derivatives.

Guo Z1, Shi T, Jiang J, Yang L, Hu W.
Organic & biomolecular chemistry.Org Biomol Chem.2009 Dec 7;7(23):5028-33. doi: 10.1039/b915013g. Epub 2009 Oct 12.
Water and ethyl diazoacetate were found to be matched components for generating highly reactive nucleophilic oxonium ylide in the presence of a dirhodium acetate catalyst. Simultaneous trapping of the oxonium ylide intermediate with aryl imines gave beta-aryl isoserine derivatives with high diastere

Carcinogenesis.Carcinogenesis.1999 Sep;20(9):1855-62.
Carboxymethylating agents are potential sources of endogenous DNA damage that have been proposed as possible contributors to gastrointestinal carcinogenesis. The cytotoxicity of the model DNA carboxymethylating agent azaserine was investigated in human cells. Expression of the DNA repair enzyme O(6)

Cancer research.Cancer Res.1989 May 1;49(9):2332-6.
Effects of sex steroids on pancreatic carcinogenesis during the early stage were studied in azaserine-treated rats of both sexes. Fischer rats were given weekly i.p. injections of azaserine (30 mg/kg) [CAS:115-02; diazoacetate serine(ester)] at 2 and 3 weeks of age and were divided into six groups.
