Attempts were made to promote the carbonyl coupling of cyclohexanone to 4-pyridylthioesters of N-carbamate-protected amino acids with the one electron reducing agent, samarium diiodide. Such reactions proved unsuccessful due to the inability of the ketyl-

The Castagnoli-Cushman reaction with benzo[d]- oxepine-2,4(1H,5H)-dione as an anhydride component allowed for preparation of 2,3-disubstituted 4-oxo-2,3,4,5-tetrahydro-1H-benzo[d]- azepine-1-carboxylic acids in 21-75% yields and with good trans diastereoselectivity. The method worked with imines generated from aromatic or a-branched aliphatic aldehydes and is amenable for both parallel synthesis and scale-up. The procedure for epimerization of the resulting trans-disubstituted tetrahydrobenzo[d]azepines to their cis isomers was also developed.
Allosteric modulators of the tertiary alkanebisamino-type. Variation of the substitution of the middle chain nitrogens
Pick, Rainer,Duda-Johner, Seraina,Traenkle, Christian,Mohr, Klaus,Holzgrabe, Ulrike
, p. 1539 - 1556 (2007/10/03)
Synthesis pathways of high flexibility for variously substituted alkanebisamine-type allosteric modulators of muscarinic receptors capable of passing the blood-brain barrier were developed starting either from N,N′-(hexane-1,6-diyl)bistosylamide or adipic
Platinum catalysed hydrolytic amidation of unactivated nitriles
Cobley, Christopher J.,Van Den Heuvel, Marco,Abbadi, Abdelilah,De Vries, Johannes G.
, p. 2467 - 2470 (2007/10/03)
The platinum(II) complex, [(Me2PO··H··OPMe2)PtH(PMe2OH)], efficiently catalyses the direct conversion of unactivated nitriles to N- substituted amides with both primary and secondary amines. Possible mechanisms for this reaction are discussed and evidence for initial amidine formation is reported. Isolated yields vary from 51-89%. (C) 2000 Elsevier Science Ltd.
