and scaleable syntheticroutes to previously unknown bifunctional tert-butyl 6-oxo-2-azaspiro[3.3]heptane-2-carboxylate are described. This compound and related intermediates described herein are useful for further selective derivation on the azetidine and cyclobutanerings providing a convenient entry point to novel compounds accessing chemical space complementary to piperidine ring systems.
