Abstract
A new two-step synthetic approach toward 3-(chloromethyl)cyclobutanone is described and used in the synthesis of 2,4-methanoproline analogues. The key step consists of a reversible addition of hydrogen cyanide onto the imines 12 in 50-74% yield under conditions that allow ring closure. 2-Alkyl-2-azabicyclo[2.1.1]hexane-1-carbonitriles 19, synthesized in four steps, can also be converted to the corresponding amines.
