  N-Alkyloxycarbonyl-3-aryloxaziridines: Their Preparation, Structure, and Utilization As Electrophilic Amination Reagents

  摘要：

  AbstractThis paper reports the synthesis of a series of N‐protected oxaziridines (N‐Moc, Boc, Z or Fmoc) and discusses their ability to deliver their N‐alkoxycar‐bonyl fragment to amines, enolates, sulfur, and phosphorus nucleophiles (electrophilic amination). These oxaziridines are prepared by oxidation of the corresponding imines with oxone or anhydrous MCPBA lithium salt as the source of oxygen. They transfer their N‐protected fragment to primary and secondary amines to give protected hydrazines in fair to excellent yield. The nitrogen transfer to free amino acids (in form of their R4N+ salts) is particularly fast, even at low temperature, providing L (or D) N‐protected α‐hydrazino acids. Enolates are C‐aminated to give N‐protected α‐amino ketones, esters, or amides in modest yield, due to a side aldol reaction of the unreacted enolate with the released benzaldehyde. With tertiary amines (Et3N), sulfides (PhSMe), and phosphines (Ph3P), amination and oxidation proceed in a parallel way; the amount of amination product increases when the temperature is lowered (kinetic control). Some of the factors that can orient the oxaziridine reactivity towards amination or oxidation of nucleophiles are considered.

  A series of novel quinidine-derived organocatalysts was synthesized and utilized for the asymmetric substitution of O-Boc-protected Morita–Baylis–Hillman adducts with various carbamates and tosylcarbamates, affording the corresponding products in good to high yields (up to 91 % yield) with moderate to high ee values (up to 96 % ee) under mild conditions.
