intermediate, cyclic disulfide (11), along with the reference diol mitomycin 7-N,7′-N′-(2″,7″-dihydroxy-1″,8″-octanediyl)bismitomycin C (23) which does not contain the disulfide unit. We found that 8 underwent significantly enhanced nucleophilic activation in the presence of Et3P compared with 23, and that the disulfide unit in 8 played a key role for the nucleophilic activation. Based on these findings
