  Synthesis of 3-Alkylbenzoxazolones from N-Alkyl-N-arylhydroxylamines by Contiguous O-Trichloroacetylation, Trichloroacetoxy ortho-Shift, and Cyclization Sequence

  摘要：

  Benzoxazolone pharmacophore is present in clinical pharmaceuticals, drug candidates, and many compounds having a wide spectrum of biological activities. The methods available for the synthesis of benzoxazolones have limited diversity due to problems in accessibility and air-sensitivity of diversely substituted o-aminophenols from which they are generally prepared by cyclocarbonylation with phosgene or its equivalents. The present paper describes a mild method for the synthesis of 3-alkylbenzoxazolones from easily accessible and air-stable nitroarenes. Nitroarenes were converted to N-alkyl-N-arylhydroxylamines in two steps involving partial reduction to arylhydroxylamines followed by selective N-alkylation. Treatment of N-alkyl-N-arylhydroxylamines with trichloroacetyl chloride and triethylamine afforded 3-alkylbenzoxazolones generally in good yields through an uninterrupted three-step sequence involving O-trichloroacetylation, N -> C-ortho trichloroacetoxy shift, and cyclization in a single pot at ambient temperatures. The present method is mild, wide in scope, economical, and regioselective. Many sensitive groups like alkyl and aryl esters, amide, cyano, and the carbon-carbon double bond survive the reaction.

  A mild and efficient dehydrative cross-coupling reaction between allylic alcohols and N-heterocycles using palladium catalysis is reported. A bicyclic bridgehead phosphoramidite (briphos) ligand together with Pd(dba)2 is a highly efficient catalyst, and an acid additive involved in the rate-determining step promotes the catalytic cycle.

• The Reaction of Dialkyl Carbonates with<i>o</i>-Aminophenol Catalysed by K₂CO₃: A Novel High-Yield Synthesis of<i>N</i>-Alkylbenzoxazol-2-ones

  At 130-150 °C and in the presence of catalytic K2CO3, o-aminophenol (1) readily reacts with dialkyl carbonates (2: ROCO2R; 2a: R = Me, 2b: Et, 2c: Allyl, 2d: Bn) to give the corresponding N-alkylbenzoxazol-2-ones (3a-d) in high yields (88-98%). This reaction is a rare example where dialkyl carbonates may simultaneously act as carbonylating and alkylating agents likely through a BAc2/BAl2 sequence. Moreover, compounds 2a-c serve also as solvents. In the case of 2d, 1,2-dimethoxyethane (DME) is the reaction medium.

  在 130-150 °C 和催化 K2CO3 存在下，邻氨基苯酚 (1) 很容易与碳酸二烷基酯（2：ROCO2R；2a：R = Me，2b：Et，2c：烯丙基，2d：Bn）反应，得到相应的N-烷基苯并恶唑-2-酮(3a-d)的产率很高(88-98%)。该反应是碳酸二烷基酯可能通过 BAc2/BAl2 序列同时充当羰基化剂和烷基化剂的罕见例子。此外，化合物2a-c也用作溶剂。在2d的情况下，1,2-二甲氧基乙烷(DME)是反应介质。
