Novel, biologically active, 5-substituted-1,3-benzoxathiol-2-ones are prepared by the reaction of 5-hydroxy-1,3-benzoxathiol-2-one with a substituted isocyanate in the presence of an activating agent and an appropriate organic solvent. The novel compounds are suitable for use as fungicides and as the active constituents in fungicidal compositions.
The present invention relates to dental polymerizable composite materials (curable dental compositions) comprising one or more plasticizers comprising a tricyclic structural element, to dental materials (polymers), obtainable by curing from the dental polymerizable composite materials comprising one or more plasticizers comprising a tricyclic structural element, to processes for producing a dental material and to dental curable composite materials for use in a therapeutic method in the production of a dental material.

Substituted pyridinols are reacted with an isocyanatoethyl alkanoate in an inert solvent in the presence of an activating agent to form a group of biologically active organic compounds. These compounds are useful as broad spectrum herbicides effective against a variety of grassy weeds, broadleaf weeds and grassy crops. Compounds of this invention may also be utilized as fungicides.
