Complete series of L-halo-and 2-cyano-cestrogens have been prepared in good to high yields: 2-chloro, 2-bromo, 2-iodo, and 2cyano derivatives via oestrogen-thallium (III) bis(trifluoroacetate) intermediates, and 2-and 4fluorooestrogens by direct kmctionalization using N-fluompyridinium triflate.

We have developed an efficient synthetic pathway to rapidly access 4-bromoindoles, 4-substituted indoles, 4-bromo-7substituted indoles, and 4,7-disubstituted indoles using a highly selective lithiation at the 7-position of 1-alkyl-4,7-dibromoindoles when treated with t-BuLi in ether. Based upon the
