The Reformatsky reagents derived from ethylbromoacetate and tert-butyl bromoacetate add cleanly, in high yield, and with good diastereoselectivity to N-tert-butanesulfinyl aldimines and ketimines. Importantly, this reaction scales well (>50 mmol), and affords products upwards of 70% yield over three steps, starting from commercially available N-tert-butanesulfinamide, aldehydes, and ketones.

日期:——
An economical, solvent-free, and metal-free method for peptidesynthesis via C–N bond cleavage using lactams has been developed. The method not only eliminates the need for condensation agents and their auxiliaries, which are essential for conventional peptidesynthesis, but also exhibits high atom economy. The reaction is versatile because it can tolerate side chains bearing a range of functional
