Novel Diels–Alder-type dimerization of 5-ethenyl-2-phenylsulfanyl-1H-imidazoles and its application to biomimetic synthesis of 12,12′-dimethylageliferin
摘要:
Diels-Alder-type dimerization of various 5-ethenyl-2-phenylsulfanyl-1H-imidazoles provided a novel highly regio- and stereoselective route to the preparation of multifunctionalized 4,5,6,7-tetrahydrobenzimidazoles, the basic skeleton of ageliferin, a biologically active pyrrole-imidazole marine alkaloid. The reaction was applied to the synthesis of 12,12'-dimethylageliferin. (C) 2002 Elsevier Science Ltd. All rights reserved.
