  Stereochemistry of the Deamination of Spiropentylamine

  摘要：

  The stereochemistry of the deamination of (-)-spiropentylamine in acetic acid has been studied, and it was found that one of the major products, (-)-spiropentyl acetate, was formed with essentially complete inversion of configuration. This suggests that it is formed via an S(N)2 displacement on the spiropentyldiazonium ion. The stereochemistry was established by the conversion of(-)-spiropentanecarboxylic acid to (-)-spiropentylamine via a Curtius rearrangement that proceeds with retention of configuration. The (-) acid also was converted to spiropentyl methyl ketone with methyllithium and then to (+)-spiropentyl acetate via the Baeyer-Villiger reaction that also results in retention of configuration. The deamination of N-nitroso-N-spiropentyl urea was studied in methanol, and spiropentyl methyl ether was a major product. Similarly, the reaction in water led to spiropentanol. The latter reactions also lead to 2-methoxymethyl- or 2-hydroxymethyl-1,3-butadiene, respectively, corresponding to the alternative mode of reaction via a cyclopropyl cation-allyl cation rearrangement.

• Pathways of decomposition of N-cyclopropyl N nitrosoureas in methanol

  Decomposition of a series of N-cyclopropyl-N-nitrosoureas (CNU) in CD3OD was studied. These decompose much more rapidly than N-methyl-N-nitrosourea, one of the decomposition pathways being denitrosation, which is atypical of alkylnitrosoureas under the reaction conditions used. The nature of substituents in the cyclopropane ring has a great effect on the stability of CNU and the product ratio. In the presence of H2 SO4, decomposition occurs much more rapidly. Possible pathways of the formation of the major decomposition products of CNU are proposed based on the experimental data.

  对一系列N-环丙基-N-亚硝基脲（CNU）在CD3OD中的降解进行了研究。它们的降解速度远快于N-甲基-N-亚硝基脲，其中一个降解途径是脱亚硝基化，这在所用反应条件下对烷基亚硝基脲而言是不典型的。环丙烷环中取代基的性质对CNU的稳定性和产物比具有很大影响。在H2SO4存在下，降解速度大大加快。根据实验数据，提出了CNU主要降解产物形成的可能途径。

  A reaction of cyclopropanediazonium ion, generated by decomposition of N-cyclopropyl-N-nitrosourea upon treatment with potassium or cesium carbonates, with various poly-hydroxyarenes and aminophenols has been studied. The reaction of azo-coupling proceeds with phloroglucinol, resorcinol, 3-methoxy- and 3-aminophenol giving rise to mono-, bis-, and tris(cyclopropylazo)arenes as the major products. Oxidizable phenols such as hydro-quinone, 2-methoxy-, 4-amino-, and 2-aminophenol give products of radical transformations with participation of cyclopropyl radical.
