  Window observers for linear systems

  摘要：

  Given a linear system (x) over dot = Ax + Bu with output y = Cx and a window function omega>(*) over bar * (t), i.e., For Allt, omega>(*) over bar * (t) is an element of {0,1}, and assuming that the window function is Lebesgue measurable, we refer to the following observer, (x) over cap = A (x) over cap + Bu + omega>(*) over bar * (t)LC(x - (x) over cap) as a window observer. The stability issue is treated in this paper. It is proven that for linear time-invariant systems, the window observer can be stabilized by an appropriate design under a very mild condition on the window functions, albeit for linear time-varying system, some regularity of the window functions is required to achieve observer designs with the asymptotic stability. The corresponding design methods are developed. An example is included to illustrate the possible applications.

  The anticonvulsant activities of functionalized N-benzyl 2-acetamidoacetamides. The importance of the 2-acetamido substituent

  摘要：

  Recent studies have demonstrated that substituted N-benzyl 2-acetamidoacetamides provide significant protection against maximal electroshock (MES)-induced seizures in mice and rats. In this study, we investigated whether the 2-acetamido moiety was necessary for anticonvulsant activity. Ten derivatives of the known anticonvulsant, N-benzyl 2-acetamido-2-phenyl acetamide were prepared in which the 2-acetamido group was replaced by hydrogen, methyl, oxygen, and halogen substituents. Evaluation of these compounds in the MES-induced seizure test demonstrated that both the hydroxy and the methoxy compounds provided full protection against MES-induced seizures in mice given ip at 100 mg/kg. Moreover, evaluation of the individual stereoisomers for the hydroxy compound showed that the principal activity resided in the (R)-isomer. These findings demonstrated that the 2-acetamido substituent is important but not obligatory for the prevention of MES-induced seizures. Further supporting evidence was provided by comparing the pharmacological activities of N-benzyl 2,3-dimethoxypropionamide with N-benzyl 2-acetamido-3-methoxypropionamide. The ED(50) value for the former in the MES test was 30 mg/kg (ip), which compared favorably with phenobarbital (ED(50) = 22 mg/kg), but the ED(50) value for N-benzyl 2-acetamido-3-methoxypropionamide was 8.3 mg/kg.

  One-carbon homologated N-(α-haloacyl)benzotriazoles have been synthesized from the corresponding aromatic and aliphatic aldehydes. Vinylbenzotriazoles, prepared by the reaction of aldehydes with the one-carbon synthon BtCH 2 P + Ph 3 Cl - , were subsequently treated with Br 2 /Et 3 N to give 1-bromovinylbenzotriazoles. These were then treated with NBS/NIS in CH 3 CN-H 2 O to furnish one-carbon homologated

  Treatment of a series of hydroxamic acids 2 with mesyl chloride in the presence of 2 equiv of triethylamine at 0-degrees-C gives 2-chloroamides 3 in good yields. Use of a single equivalent of triethylamine gives the (N-mesyl-oxy)amides 1, which are versatile synthetic intermediates as they can be readily converted to 2-bromoamides 4 with lithium bromide and triethylamine and to 2-hydroxyamides 5 with triethylamine in aqueous acetonitrile.
