  Asymmetric organocatalytic Mannich reaction of α-azido ketones and N-Boc protected isatin-derived ketimines were investigated for the first time. Examination of both 2-adamantyl and 3,5-bis(trifluoromethyl)aniline substituted quinine-based squaramides afforded chiral Mannich bases with two contiguous stereogenic centers in high yields (up to 97%) and stereoselectivity (up to dr = 24 : 1 syn : anti

  Carbanions generated from various acyclic and cyclic α-azido ketones in the presence of bases were reacted with ethyl 3-[(carbamoylimino)amino]but-2-enoate as a Michael acceptor to give the corresponding adducts. The adducts of acyclic azides were unstable and eliminated hydrazoic acid to give the corresponding ethyl 2-[1-[(carbamoylamino)imino]ethyl]-4-oxo-4-phenylbut-2- enoates as (E,E/Z,E)-diastereomeric

• Base-Promoted Reactions of .alpha.-Azido Ketones with Aldehydes and Ketones: A Novel Entry to .alpha.-Azido-.beta.-hydroxy Ketones and 2,5-Dihydro-5-hydroxyoxazoles

  DOI：10.1021/jo00113a015

  日期：1995.4

  The base-promoted reaction of alpha-azido ketones with aldehydes and ketones provides a new and simple route to either alpha-azido-beta-hydroxy ketones, which are valuable 1,2,3-trifunctionalized synthons, or 2,5-dihydro-5-hydroxyoxazoles, which are a little known type of oxazoline. These two products are formed by the electrophilic trapping of two different anions that are produced sequentially during the reaction, The alpha-azido-beta-hydroxy ketones are formed by an aldol reaction between an enolate of the alpha-azidoketone and an aldehyde. The 2,5-dihydro-5-hydroxyoxazoles are formed by electrophilic trapping of an imino anion which is produced by nitrogen loss from the cx-azido ketone enolate.
