Gold-catalyzed oxycyclization of allenic carbamates: expeditious synthesis of 1,3-oxazin-2-ones
نویسندگان
چکیده
A combined experimental and computational study on regioselective gold-catalyzed synthetic routes to 1,3-oxazinan-2-ones (kinetically controlled products) and 1,3-oxazin-2-one derivatives (thermodynamically favored) from easily accessible allenic carbamates has been carried out.

Gold-catalyzed cyclization reactions of allenol and alkynol derivatives.
Although gold is chemically inert as a bulk metal, the landmark discovery that gold nanoparticles can be effective catalysts has opened up new and exciting research opportunities in the field. In recent years, there has been growth in the number of reactions catalyzed by gold complexes [gold(I) and gold(III)], usually as homogeneous catalysts, because they are soft Lewis acids. In addition, alk...

A mild and convenient one-step preparation of 4H-1,3-benzoxazin-4-ones by a domino carbonylation-cyclization process is developed. Readily available ortho-iodophenols are subjected to palladium-catalyzed carbonylative coupling with Mo(CO)6 and cyanamide, followed by a spontaneous, intramolecular cyclization to afford 4H-1,3-benzoxazin-4-ones in moderate to excellent yields. Furthermore, the sco...
متن کاملCopper-catalyzed tandem aryl-halogen hydroxylation and CH2Cl2-based N,O-acetalization toward the synthesis of 2,3-dihydrobenzoxazinones.
The concise synthesis of 2,3-dihydro-4H-benzo[e][1,3]oxazin-4-ones has been accomplished by copper-catalyzed tandem reactions of o-halobenzamides, LiOH and dichloromethane. The aryl-halogen bond hydroxylation and subsequent N,O-acetalization on CH2Cl2 are enabled under catalytic conditions which allows the generation of C(sp2)-O, C(sp3)-O and C(sp3)-N bonds to give the target products.
