TOTAL SYNTHESIS OF LYNGBYATOXIN A (TELEOCIDIN A-1) AND TELEOCIDIN A-2

An eleven step synthesis of tumor promoters, lyngbyatoxin A (=teleocidin A-1) (1) and teleocidin A-2 (2) was achieved from 1-tosylpyrrole (4) using a novel reaction forming 7-alkyl-4-aminoindoles (11).

PREPARATION OF ALKYL-SUBSTITUTED INDOLES IN THE BENZENE PORTION. Part 3

Three-step synthesis of 7- and 4-alkyl-1-tosylindoles (9 and 10) was accomplished by combination of the Friedel-Crafts acylation of 4, and the treatment of 7 and 8 with H2SO4 in 2-propanol as illustrated in Chart 2.Further a novel synthetic method of 16 was devised from 14 by way of 15.
