Chemistry is traditionally divided into organic and inorganic chemistry. Recommanded Product: 2-Chloroquinoxaline, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 1448-87-9
An efficient approach to synthesis of various substituted 3-azabicyclo[3.2.0]heptane-derived building blocks based on [3+2] cycloaddition of cyclobut-1-eneraboxylic acid ester and in situ generated azomethine ylide was developed and applied on multigram scale. The utility of 1,3-disubstituted 3-azabicyclo[3.2.0]heptane scaffold was demonstrated by additional structural analysis using exit vector plot (EVP) tool, and tested in parallel synthesis of compound library.
