Synthesis of 3,3,3-trifluoroprop-1-enyl compounds from some enolizable aldehydes
摘要:
2,2,2-Trifluoroethyldiphenylphosphine oxide [Ph2P(O)CH2CF3] (2) is known to give no Homer reaction product with enolizable aldehydes. We found, however, that some enolizable aldehydes such as N-Boc-pyrrolidine-2-aldehyde (9) gave the expected 3,3,3trifluoroprop-1-enyl compounds by reaction with 2. The products could be further transformed to some 2,2,2-trifluoroethyl-substituted nitrogen-containing heterocycles by using radical cyclization or Heck reaction. (C) 2004 Elsevier Ltd.

The invention relates to novel benzodiazepine derivatives with antiproliferative activity and more specifically to novel benzodiazepines of formula (I) and (II), in which the diazepine ring (B) is fused with a heterocyclic ring (CD), wherein the heterocyclic ring is bicyclic or a compound of formula (III), in which the diazepine ring (B) is fused with a heterocyclic ring (C), wherein the heterocyclic ring is monocyclic. The invention provides cytotoxic dimers of these compounds. The invention also provides conjugates of the monomers and the dimers. The invention further provides compositions and methods useful for inhibiting abnormal cell growth or treating a proliferative disorder in a mammal using the compounds or conjugates of the invention. The invention further relates to methods of using the compounds or conjugates for in vitro, in situ, and in vivo diagnosis or treatment of mammalian cells, or associated pathological conditions.

Highly enantioselective hydrogenation of N-protected indoles was successfully developed by use of the rhodium catalyst generated in situ from [Rh(nbd)2]SbF6 and the chiralbisphosphine PhTRAP, which can form a trans-chelate complex with a transition metal atom. The PhTRAP–rhodium catalyst required a base (e.g., Cs2CO3) for the achievement of high enantioselectivity. Various 2-substituted N-acetylindoles
通过使用由[Rh(nbd)2 ] SbF 6原位生成的铑催化剂和手性双膦PhTRAP,可以成功地开发出N-保护的吲哚的高度对映选择性氢化反应,可以与过渡金属原子形成反式-螯合物。PhTRAP-铑催化剂需要碱(例如Cs 2 CO 3)才能实现高对映选择性。将各种2-取代的N-乙酰吲哚转化为具有高达95%ee的相应的手性二氢吲哚。3-取代的N - tosylindoles的氢化产生二氢吲哚,其在3-位具有立体异构中心,具有高的对映异构体过量(至多98%ee)。
