SYSNTHESIS OF SECOISOQUINOLINE ALKALOIDS TOTAL SYNTHESIS OF CRYPTOPLEUROSPERMINE
Rozwadowska, Maria D.,Chrzanowska, Maria
, p. 6669 - 6672 (1986)
Cryptopleurospermine (1), a 1,2-secobenzylisoquinoline alkaloid was synthesized from hydrastinine derivative 2 and isovanillin 1,3-propylene dithioacetal 3.The formation of C-C bond between these two synthons involved addition of dilithio salt of dithian
