A series of 5-arylisoxazole (II) and related pyrazole derivatives (III) are synthesized via ultrasound assisted reactions of 3-aminopropenone (I) with hydroxylamine or hydrazine hydrate, respectively. [ABSTRACT FROM AUTHOR]

Reaction of isonitriles with 3-(arylamino)isobenzofuran-1(3H)-ones in the presence of a catalytic amount of an octahydro (R)-binol-derived chiral phosphoric acid affords 3-oxo-2-arylisoindoline-1-carboxamides in high yields with good to high enantioselectivities. [ABSTRACT FROM AUTHOR]

A convenient microwave promoted three‐component domino reaction of β‐ketoamides (I), pentandial (II), and malononitrile (III) is developed to give deca‐ and octahydroisoquinolines (IV) and (VI). [ABSTRACT FROM AUTHOR]

The reaction has a good functional group tolerance and can be scaled up. [ABSTRACT FROM AUTHOR]

22 Title compounds of type (III) or (IV) are prepared in relatively short reaction times. [ABSTRACT FROM AUTHOR]

The synthesis of a large variety of the desired heterocyclic structures becomes possible under microwaves with high regio- and chemoselectivity. [ABSTRACT FROM AUTHOR]

This unusual reaction is performed in tetrahydrofuran which is split during the reaction in an unprecedented manner under conditions used, leading to the formation of two geminal C-C bonds via C-H and C-O cleavage. [ABSTRACT FROM AUTHOR]
