Heterocyclic ring-analogs of dihydropyridine calcium antagonists
Taylor,Anderson,Badger
, p. 1353 - 1356 (1989)
An improved synthesis of the 1,4-dihydropyrazine derivative, 3, is described that involves the versatile 1,4-diketointermediate, 9. This intermediate was converted to several heterocyclic ring-analogs of 1,4-dihydropyridine in addition to 3 including deri
Combinatorial Synthesis of Functionalized 1,3-Thiazine Libraries Using a Combined Polymer-Supported Reagent/Catch-and-Release Strategy
Strohmeier, Gernot A.,Kappe, C. Oliver

A dual role: The supported sulfonic acid reagent promotes the ring closure of the thiazine products and also binds them in situ as ion pairs (see scheme). The nonbasic by-products and excess reagents can be removed by filtration and the products subsequen
