experimental part, p. 351 - 354 (2009/07/19)
A simple and efficient synthesis of 1(2H)-phthalazinone derivatives was achieved via reaction of phthalaldehydic acid and various phenyl hydrazines in acetonitrile using HClO4-SiO2 as a catalyst in very good yields.
Preparation and cycloaddition reactions of novel heterocyclic mesomeric betaines
Morgan, David O.,David Ollis,Stanforth, Stephen P.
, p. 5523 - 5534 (2007/10/03)
The heterocyclic mesomeric betaines 6a-c reacted with dimethyl acetylenedicarboxylate and ethyl propiolate giving the 1,3-dipolar cycloaddition products 7a-c and 8a-c, respectively. With esters of maleic, fumaric, acrylic and methacrylic acids, mesomeric betaines 6a and 6b gave substituted tetralone derivatives. (C) 2000 Elsevier Science Ltd.
