Practical Asymmetric Synthesis of α-Branched 2-Piperazinylbenzylamines by 1,2-Additions of Organometallic Reagents to N-tert-Butanesulfinyl Imines

2-[4-(tert-Butoxycarbonyl)piperazinyl]benzylidene-tert-butanesulfinamides underwent nucleophilic 1,2-addition with different organometallic reagents to give highly diastereomerically enriched adducts. X-ray crystallography of the resulting α-branched N-Boc-2-piperazinylbenzyl-tert-butanesulfinamides...
