    Notes: Abstract Chaotic dynamics arises when the unstable manifold of a hyperbolic equilibrium point changes its twist type along a homoclinic orbit as some generic parameter is varied. Such bifurcation points occur naturally in singularly perturbed systems. Some quotient symbolic systems induced from the Bernoulli symbolic system on two symbols are proved to be characteristic for this new mechanism of chaos generation. Combination of geometrical and analytical methods is proved to be more fruitful.

    Notes: Some 3-methoxyflavones were known to possess antipicornavirus properties. In order to study the structure-activity relationship, attempts to prepare 3-methoxyflavone by literature methods were unsuccessful. We have modified the Baker-Venkataraman rearrangement, using a solid base and a phase-transfer catalyst. After searching optimal reaction conditions and a study of the intermediate formed in a model reaction, good yields were obtained for the 3-methoxyflavones 7, 21-32. Further some of the corresponding 7-O-n-butyl derivatives 4, 33-37 could be isolated as side products.
