supporting information; experimental part, p. 4275 - 4278 (2009/05/30)
(Chemical Equation Presented) A sequential metal-catalyzed C-N bond formation employing ortho-haloaryl acetylenic bromides is described. The initial amidation is highly selective for C8P-N bond formation, leading to o-haloaryl-substiluted ynami

A novel efficient catalytic approach to steroids by a double Heck reaction of the vinyl bromides 2 and the CD-building block 3 is presented. The new estrogen analogues 1a and 1b are formed via 23a and 23b in a highly regio- and stereoselective manner in g
