CHOLESTENO INDOLES .1. PREPARATION OF 1'H -5-ALPHA-CHOLEST-2-ENO[3,2-B]INDOLES

1'H-5alpha-Cholest-2-eno[3,2-b]indole (1a), the corresponding N-methyl , N-acetyl, and N-formyl compounds 1b-d, as well as the respective met hoxy derivatives 2b-5d have been synthesized as model compounds for in tended CD investigations. Application of the Fischer indole synthesis afforded the compounds 1a-5a which were N-methylated to 1b-5b, N-acety lated to 1c-5c, and N-formylated to 1d-5d.
