Using a commercially available, inexpensive, and abundant copper catalyst system, an efficient α-functionalization of nitroalkanes with propargyl bromides is now established. This mild and robust method is highly functional group tolerant and provides straightforward access to complex secondary and tertiary homopropargylic nitroalkanes. Moreover, the utility of these α-propargylated nitroalkanes is demonstrated through downstream functionalization to biologically relevant, five-membered N-heterocycles such as pyrroles and 2-pyrrolines.
A tert-butoxy carbonyl N - -4 - nitro-piperidine preparation method

Paragraph 0019; 0021, (2017/05/26)
The invention relates to a preparing method of N-t-butyloxycarboryl-4-nitro piperidine. The method mainly solves the technical problems that in an existing synthetic process, the route is long, yield is low, reaction is not easy to control, experimental operation is inconvenient, and the like. According to the method, N-t-butyloxycarboryl-4-hydroxy piperidine is used as raw material to prepare N-t-butyloxycarboryl-4-iodine piperidine, and further the target product is obtained through the substitution reaction. The N-t-butyloxycarboryl-4-nitro piperidine obtained with the method is a useful intermediate or product used for synthesis of various kinds of drugs.
