The structures of sulfomycin I and berninamycin A

Hiroshi Abe; Katsuhiko Kushida; Yoshinori Shiobara; Mitsuaki Kodama

Abstract The structure of sulfomycin I, a modified peptide antibiotic, was determined on the basis of chemical and sepctroscopic evidence. The revised structure of structurally related antibiotic, berninamycin A, was also proposed.


Tetrahedron Letters | 1994

Synthesis and structure of nitrene-C60 adduct, C60NPhth (Phth=Phthalimido)

Shin-ya Kuwashima; Masayuki Kubota; Katsuhiko Kushida; Takayuki Ishida; Mamoru Ohashi; Takashi Nogami

Abstract Phthalimidonitrene (:NPhth) generated from H 2 NPhth and lead tetraacetate in chlorobenzene was found to add to C 60 , affording C 60 (NPhth) n (n=1–4). The adducts were separated, and the mono-adduct was spectroscopically characterized as an aziridine structure at a 6/6-ring junction. The electron affinity and aziridine inversion are significantly influenced by the substituents on the aziridine nitrogen.
