Aza-Henry reaction of substituted nitroalkanes using α-formamidoaryl sulfones as N-acylimino equivalents
摘要:
Base-promoted elimination of p-toluenesulfinic acid from N-formamidoaryl sulfones leads to the corresponding N-acylimines that react with primary and secondary nitronate anions giving anti-beta-formamido nitroderivatives in good yields and high diastereoselectivity.

Copper-catalyzedintermolecular aminoazidation of alkenes is described. This novel methodology provides an efficient approach to vicinal amino azides which can easily be transformed into other valuable amine derivatives. The commercially available N-fluorobenzenesulfonimide (NFSI) is used as a nitrogen-radical precursor and TMSN3 as the N3 source. Yields are moderate to excellent, and for internal

A new simple procedure for the synthesis of diastereomeric 1,2-diamino-1-phenylpropanes starting from u-N-trifluoroacetyl-2-amino-1-phenylpropan-1-ol (N-trifluoroacetylnorephedrine) is described. The trifluoroacetyl protecting group was particularly suitable for the protection of the amino group in order to reduce side reactions.
