Journal ArticleDOI
Rhodium(II)-catalyzed aziridination of allyl-substituted sulfonamides and carbamates.
TL;DR: The expected aziridine was not observed, but rather simultaneous spirocyclization of C(3) and stereoselective syn-acylation at C(2) occurred to give compound 41, whose structure was unequivocally established by an X-ray crystallographic study.
Journal ArticleDOI
Stereochemical aspects of the iodine(III)-mediated aziridination reaction of some cyclic allylic carbamates.
Albert Padwa,Thomas Stengel +1 more
TL;DR: The iodine(III)-mediated aziridination reaction of an indolyl-substituted carbamate requires a Rh(II) catalyst and proceeds by a metallonitrene intermediate, which ultimately leads to the observed products.
Journal ArticleDOI
Transition metal catalyzed ring opening reactions of 2-phenyl-3-vinyl substituted 2H-azirines
Albert Padwa,Thomas Stengel +1 more
TL;DR: In this paper, a 2-phenyl-3-vinyl-substituted 2H-azirines were treated with Grubbs' catalyst to obtain α,β-unsaturated oxime.
Journal ArticleDOI
Rhodium(II)‐Catalyzed Aziridination of Allyl‐Substituted Sulfonamides and Carbamates.
TL;DR: In this paper, the azabicyclic sulfonamides in methanol in the presence of p-TsOH were treated with PhI(OAc)(2), MgO, and catalytic Rh(2)(OAc(4) to give bicyclic aziridines in excellent yield.
Journal ArticleDOI
Stereochemical Aspects of the Iodine(III)‐Mediated Aziridination Reaction of Some Cyclic Allylic Carbamates.
Albert Padwa,Thomas Stengel +1 more
TL;DR: In this paper, the IBE reaction of cycloalkenyl carbamates does not require a Rh(II) catalyst and occurs via an iminoiodinane intermediate.
