Synthesis of several new tetracyclic heteroaromatic chromans has been achieved through the reaction of various uracil and 1,3-thiazine derivatives with 1,2-naphthoquinone-1-methide. The spirodimer 4 is a better source of naphthoquinone methide than the naphthol derivatives which provide chromans in low yield due to side reactions. The structure and mechanisms of the various products formed are discussed
The present invention provides ion-selective electrode (ISE) sensors for detecting one or more analytes in a sample that includes an electrode and an ion-selective membrane, wherein the ion selective membrane contains an epoxy resin and one or more amine curing agents. The invention also provides methods of making and using such ISE sensors.
