✦ Synopsis

Two new istamycin components have been isolated from culture filtrates of Streptomyces tenjimariensis. Their structures were suggested to be 2"-N-formimidoylistamycins A and B by spectral analysis, and confirmed by synthesis starting from istamycins A, and BO, respectively. *Dedicated to Professor Sumio Umezawa on the occasion of his 73rd birthday and the 25th anniversary of the Microbial Chemistry Research Foundation. tTo whom correspondence should be addressed.
