  Divergent Reactivity in the Reaction of β-Oxodithioesters and Hydroxylamine: Access to β-Ketonitriles and Isoxazoles

  摘要：

  Starting from beta-oxodithioesters and hydroxylamine, two completely different transformations afford either beta-ketonitriles or isoxazoles with high chemoselectivity depending on the reaction conditions. The reaction of beta-oxodithioesters with hydroxylamine in EtOH at room temperature in daylight gave beta-ketonitriles in high yields. On the other hand, 3-methylthio-isoxazoles were efficiently obtained as the final products by heating the mixture of beta-oxodithioesters and hydroxylamine in HOAc at 90 degrees C.

  −NO2, −SO2Ar, and −COAr were also successful. In addition, reaction with heterocyclic compounds such as 3‐(3‐bromothiophen‐2‐yl)‐3‐oxopropanenitrile proceeded smoothly to afford tetrahydrothieno[3,2‐b]pyridine‐6‐carbonitrile analogues. The practicality of the designed protocol was confirmed by gram scale synthesis of two derivatives.

  The copper‐catalyzed decarboxylative [3+2] annulation of ethynyl benzoxazinanones with 3‐oxo‐3‐arylpropanenitriles has been developed, producing tetrasubstituted furan derivatives in moderate to high yield. This reaction was generally compatible with a wide range of substrates. Notably, the intermediate copper‐allenylidenes worked as a C2 synthon in the cycloaddition reaction.

  An asymmetric Michael addition of α-cyanoketones to α,β-unsaturated aldehydes to form chiral dihydropyrans catalyzed by l-diphenylprolinol trimethylsilyl ether is presented. A series of 3,4-dihydropyrans were obtained in excellent yields (up to 91%) and enantioselectivities (up to 98% ee). A plausible mechanism for this process is proposed.

  condensation of benzoate esters with alkyl- or phenylacetonitriles lead to 3-aminoindenones in the presence of excess LDA. This new reaction is also applicable to pyridine carboxylic esters. All of the 3-aminoindenones and their aza analogues can be hydrolyzed by acid to give the corresponding 1,3-indandiones. The mechanism of the reaction falls into the directed-ortho-metalation class in which the initial
