We synthesized benzolactams with hydrophobic substituents at various positions as analogs of (-)-benzolactam-V8-310 ((-)-BL-V8-310, 1) which reproduces the active conformation and biological activity of teleocidins. Structure-activity data indicate that the existence of a hydrophobic region between C-2 and C-9, and the steric factor at C-8 play critical roles in the appearance of biological activities.

structures and the activities of these compounds has attracted much attention because of the marked structural dissimilarities. The benzolactam 5, with an eight-membered lactam ring and benzene ring instead of the nine-membered lactam ring and indole ring of teleocidins, reproduces the active ring conformation and biological activities of teleocidins. Herein we describe the synthesis of benzolactams with
