✦ Synopsis


A mild and general method for the synthesis of dimethylallyl tryptophan derivatives 11 and 12 is described. Reaction of the 3-(r,X-dimethyl-allyl) indoles i'a or 7b with the nitroso olefin 8 yields the cycloadducts 9a (93%) and 9b (87%), respectively. Subsequent treatment of 9a with trifluoroacetic

A practical synthesis of pyrrolo [3,2-e]indole (1) is described. Different hydrogenation conditions of the indol-4-ylacetonitrile (3) afforded either l-BOM-pyrrolo[3,2-e]indole (4, 42% from 5nitroindole) or I-hydroxymethylpyrrolo[3,2-e]indole (5, 46% from 5-nitroindole). Removal of the benzyl group
