Synthesis of a series of novel fused pyrazolines and pyrazoles has been accomplished in good yields by regio- and diastereoselective 1,3-dipolar cycloaddition of enamines of indan-1-one 1a-c towards C-aryl-N-phenylnitrilimines 2d- f. The structure of

Some 4-substituted arylnitrile oxides and (Z)-3-arylidene-2(3H)-benzo-furanones undergo 1,3-dipolar cycloaddition reactions to give exclusively spirodihydroisoxazoles. These spiroadducts have be opened to the corresponding ethyl 3,4-diaryl-5-(orthohy

Autor: Karin Monnier‐Jobe, Bernard Laude, Sandrine Perrin, Sylvain Burger
Publikováno v: Journal of Chemical Research. 2002:355-356
A new and convenient procedure for the preparation of 3,6-diaryl-2(1 H)-pyridones via 1,3-dipolar cycloaddition of münchnonimines to acrylic esters is described.
