Webtion of the carcinogenic “bay region diol epoxide,” anti-BaP-7,8-diol-9,10-epoxide (BPDE), illustrated in Fig. 1A (Conney, 1982; Cooper et al., 1983; Dipple et al., 1984). BPDE reacts easily with DNA to form adducts that cause miscoding and mutations. These adducts are crucial factors in its mechanism of carcinogenesis. There are opposing de- WebTHF (7.7 vol.), and cooled to an internal temperature of -20 C. A solution of ER-806049 (1 wt, 1 eq.) in THF (2.3 vol.) was added keeping the internal temperature below - 7 C. Neat BnBr was added, maintaining -7 C as the maximum temperature. The reaction was stirred at -20 C for 2 hours and 10 hours at 10 C. The reaction was quenched with 10%
