Efficient and practical method for synthesizing optically active indan-2-ols by the Ti(O-i-Pr)(4)/2 i-PrMgCl-mediated metalative Reppe Reaction.
The Journal of organic chemistry, 2003Co-Authors: Takeshi Hanazawa, Kousuke Sasaki, Yuuki Takayama, Fumie SatoAbstract:An efficient and practical synthesis of optically active indan-2-ols 1 has been developed starting from readily accessible optically active 4-siloxy-1,6-alkadiynes 2 and ethynyl p-tolyl sulfone, where the metalative Reppe Reaction mediated by an economical divalent titanium reagent, Ti(O-i-Pr)4/2 i-PrMgCl, is a key step.

Selective preparation of benzyltitanium compounds by the metalative Reppe Reaction. Its application to the first synthesis of alcyopterosin A.
Journal of the American Chemical Society, 2002Co-Authors: Ryoichi Tanaka, Yoshitaka Nakano, Daisuke Suzuki, And Hirokazu Urabe, Fumie SatoAbstract:Dialkoxytitanacyclopentadienes, prepared from two different acetylenes and a divalent titanium alkoxide reagent, Ti(O-i-Pr)4/2 i-PrMgCl, reacted with propargyl bromide to give directly benzyltitanium compounds. The resultant benzyltitanium compounds underwent deuteriolysis, iodinolysis (with I2), or oxygenation (with O2 gas) to give the corresponding deuterium-labeled compounds, iodides, or alcohols, illustrating their synthetic versatility. The first synthesis of alcyopterosin A, a bicyclic aromatic sesquiterpenoid recently isolated and characterized, has been achieved by this method, starting with an appropriate combination of an acetylene and a diyne.
