Acylimine mediated N N bond cleavage of pyrazolidinediones and subsequent conversion to dihydropyrimidinediones and malonamides
摘要:
Acylimines 3 were identified as intermediates in the fluorenyl assisted N-N bond cleavage of pyrazolidinediones 1. Subsequent conversion of 3 to dihydropyrimidinediones 4 and malonamides 7-10 is described. (C) 2000 Published by Elsevier Science Ltd.
