development of a simple, high yielding and stereocontrolled strategy for the synthesis of a series of triazolopiperazines and other biologically relevant fused scaffolds from optically active amino acids. This route was applied to the synthesis of 22 scaffolds containingnew, previously inaccessible vectors and used to access a novel analogue of ganaplacide.

The introduction of an unsubstituted cyclopropyl moiety was efficiently accomplished via Negishi cross-coupling of cyclopropylzinc bromide with functionalized aryl halides in high yields and fast reaction rates. The stability and the efficient one-step synthesis of cyclopropylzinc bromide make this protocol very valuable in particular for commercial applications.
effect and the partial rate factor, the cyclopropylradical seems to be fairly free from polar effect, and to resemble the phenyl radical more than the common alkyl radical although the cyclopropylradical has a slightly higher reactivity than the phenyl radical. The relative reactivity of the 2-phenylcyclopropyl radical in the hydrogen abstraction reaction toward the benzylic position of ring-substituted
