A New Entry into 2-Azabicyclo[2.1.1]hexanes via 3-(Chloromethyl)cyclobutanone was written by Stevens, Christian;De Kimpe, Norbert. And the article was included in Journal of Organic Chemistry in 1996.Safety of Methyl 3,3-dimethoxycyclobutanecarboxylate This article mentions the following:
2-Azabicyclo[2.1.1]hexanes, which possess the skeleton of 2,4-methanoproline (a naturally occurring insect antifeedant), were synthesized by imination of the previously unknown 3-(chloromethyl)cyclobutanone and subsequent reductive cyclization. The precursor of the latter, 3-oxocyclobutane-1-carboxylic acid, was prepared by two pathways in multigram quantities. In the experiment, the researchers used many compounds, for example, Methyl 3,3-dimethoxycyclobutanecarboxylate (cas: 98231-07-3Safety of Methyl 3,3-dimethoxycyclobutanecarboxylate).
Methyl 3,3-dimethoxycyclobutanecarboxylate (cas: 98231-07-3) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Safety of Methyl 3,3-dimethoxycyclobutanecarboxylate
