M. Tercel et Wa. Denny, SYNTHESIS OF NITROGEN AND SULFUR ANALOGS OF THE SECO-CI ALKYLATING AGENT, Journal of the Chemical Society. Perkin transactions. I, (3), 1998, pp. 509-519
Two complementary syntheses of amino seco-CI (CI = a,2,3,5-tetrahydro-
1H-cycloprop[1,2-c]indol-5-one) alkylating agents starting from isomer
ic chloronitrobenzoic acids are reported. Further reactions of these c
ompounds, including diazotisation to phenol and thiophenol derivatives
, and alkylation and acylation reactions relevant to the preparation o
f pro-drug forms are also described.
