The invention relates to N-sulfonyl-&#x3b1;-amino-acetic acid derivatives of the general formula (I): including the optical isomers thereof and mixtures of such isomers, wherein Arand Arindependently of each other stand for an optionally substituted aryl or heteroaryl group, Rand Rstand independently of each other for hydrogen, optionally substituted C-Calkyl, optionally substituted C-Calkenyl, C-Calkynyl or optionally substituted CCCycloalkyl; Rdesignates hydrogen, C-Calkenyl, C-Calkynyl or optionally substituted C-Calkyl; Ris optionally substituted C-Calkyl, optionally substituted C-Calkenyl, C-Caklynyl or optionally substituted C-Ccycloalkyl; Rand Rare independently of each other hydrogen or optionally substituted C-Calkyl, optionally substituted C-Calkenyl, C-Calkynyl or optionally substituted C-Ccycloalkyl; Rand Rare independently of each other hydrogen or optionally substituted C-Calkyl, optionally substituted C-Calkenyl, C-Calkynyl or optionally substituted C-Ccycloalkyl; W designates a bridge selected from &#x2014;O&#x2014;, &#x2014;S&#x2014;, &#x2014;SO&#x2014;, &#x2014;SO&#x2014; or is an &#x2014;NH&#x2014; or &#x2014;N(C-Calkyl)-bridge; X designates a direct bond or a bridge selected from &#x2014;O&#x2014;, &#x2014;S&#x2014;, &#x2014;SO&#x2014;, &#x2014;SO&#x2014; or is an &#x2014;NH or &#x2014;N(CCalkyl)-bridge; Y designates &#x2014;ORor NRR; a and b independently of each other stand for a number 1, 2 or 3; and c stands for a number zero, 1 or 2; with R, Rand Rbeing defined according to the claims. These compounds possess useful plant protecting properties and may advantageously be employed in agricultural practice for controlling or preventing the infestation of plants by phytopathogenic microorganisms, especially fungi. 

N-sulfonyl-&#x3b1;-amino-acid derivatives

The invention relates to &#x3b1;-sulfonylamino-acetonitrile derivatives of the general formula (I) including the optical isomers thereof and mixtures of such isomers, wherein Ar, and Arindependently of each other stand for an optionally substituted aryl or heteroaryl group, R, and Rstand independently of each other for hydrogen, optionally substituted C,-Calkyl, optionally substituted C-Calkenyl, C-Calkynyl or optionally substituted C-Ccycloalkyl; Rdesignates hydrogen, C-Calkenyl, C-Calkynyl or optionally substituted C,-Calkyl; Ris optionally substituted C,-Calkyl, optionally substituted C-Calkenyl, C-Calkynyl or optionally substituted C-Ccycloalkyl; Rand Rare independently of each other hydrogen or optionally substituted C-Calkyl, optionally substituted C-Calkenyl, C-Calkynyl or optionally substituted C-Ccycloalkyl; R, and Rare independently of each other hydrogen or optionally substituted C,-Calkyl, optionally substituted C-Calkenyl, C-Calkynyl or optionally substituted C-Ccycloalkyl; W designates a bridge selected from &#x2014;O&#x2014; &#x2014;S(O)m&#x2014; or &#x2014;NR&#x2014;; X designates a direct bond or a bridge selected from &#x2014;O&#x2014;, &#x2014;S(O)m&#x2014; or &#x2014;NR&#x2014;; a and b independently of each other stand for a number 1, 2 or 3; and c and m independently of each other stand for a number zero, 1 or 2. These compounds possess useful plant protecting properties and may advantageously be employed in agricultural practice for controlling or preventing the infestation of plants by phytopathogenic microorganisms, especially fungi.

Alpha-sulfonylamino-acetonitriles

A snow glider in the form of an elongated glide plate (1), the upper side of which has at least one stand-on area (2, 3) for the feet of the user and the front part of which is bent upwards in the manner of ski tips. The glide plate (1) is wider at the rear than at the front and in the middle, this wider rear part (6) being bent upwards out of the plane of the middle part (5). The snow glider makes free smooth running on snow possible, changes in the direction of running being effected by a corresponding shift of the center of gravity of the body.
