The new 1,1-dimethylpropargylamine surrogates, 1-ethynylcyclopropylamine (3) and 1-ethynylcyclobutylamine (5), were prepared as hydrochlorides from cyclopropylacetylene and 6-chlorohex-1-yne in overall yields of 39 and 25%, respectively, on a scale of up to 300 mmol. The amine 3 was converted into the new ethynyl-extended 1-aminocyclopropanecarboxylic acid 4, and both the amine 3 as well as the amino acid 4 were made available as their N-Fmoc-protected derivatives.

An endo-directing group strategy enables enantioselective (3+1+2) cycloadditions that are triggered by carbonylative C−C bond activation of cyclopropanes. These processes are rare examples of cycloadditions where C−C bond oxidative addition is enantiodetermining.
