  UV-induced isomerisation and ring transformation of (E)-3-arylidene-1-thiochromanones and -1-thioflavanones

  摘要：

  Depending on the substituent of the arylidene moiety, photoisomerisation of (E)-3-arylidene-1-thiochroman-4-ones 1 and 3 afforded either the expected (Z)-1 and (Z)-3 isomers or the products (2d,e and 4c,d) of an unprecedented phototransformation.

  Spiropyrazolines have been synthesized by 1,3-dipolar cycloaddition of an 2-arylidene-1-tetralone, 3-arylidene-chromanones, -1-thiochromanones, and -flavanones with diazomethane. The relative configuration and stereochemistry of the products have been determined by means of one-dimensional difference N.O.E. measurements. It is shown that ring-closure reaction is regioselective, yielding stereohomogeneous

  Stereoselective synthesis of trans-2,3,3a,4-tetrahydro-3-aryl-2-phenyl[1]benzopyrano[4,3-c]pyrazoles 13–18 and their [1]benzothiopyrano analogues 19–24 has been performed by the reaction of 3-arylidenechromanones 1–6 and 3-arylidene-1-thiochromanones 7–12 with phenylhydrazine in hot pyridine. The structure and stereochemistry of the compounds prepared have been elucidated by ir, lH and 13C nmr measurements
