-The nitrogen-radical precursors (10-15) have been prepared and subjected to reaction conditions expected to promote tandem radical cyclization sequences leading to the CDE-tricyclic frameworks associated with alkaloids such as vindoline (1) and ibophyllidine (2). In the event, each of precursors (10, 11, 12 and 13) participated in the desired processes and thus providing products, (28, 29, 30 and 31) respectively, embodying ring systems related to ibophyllidine (2). In contrast, the higher...[Show more]
