Kocak, Ramazan,Dastan, Arif,Saracoglu, Nurullah
, p. 1489 - 1493 (2018/06/20)
Syntheses of pyridazine and pyrrole analogues of 2-aminotetralin starting from 3-cyclohexene-1-carboxylic acid are reported. All syntheses involve the following key steps: Curtius rearrangement for amine functionality, inverse electron demand Diels–Alder
Palladium- and ruthenium-catalyzed cycloisomerization of enynamides and enynhydrazides: A rapid approach to diverse azacyclic frameworks

I want to ride my azacycle: The title reaction of enynamides affords a wide diversity of azacycles. The reactions are high-yielding, highly stereoselective, and proceed rapidly under mild reaction conditions. Equivalent transformations using enynhydrazides offer new routes to pyrazole and indazole scaffolds.

The synthesis of new 7-azabicyclo[2.2.1]heptane derivatives has been achieved in a four-step synthetic sequence, starting from readily available cyclohex-3-enecarboxylic acid, Curtius reaction, stereoselective bromination leading to major benzyl(cis-3, tr
Scope of the directed dihydroxylation: Application to cyclic homoallylic alcohols and trihaloacetamides
Donohoe, Timothy J.,Mitchell, Lee,Waring, Michael J.,Helliwell, Madeleine,Bell, Andrew,Newcombe, Nicholas J.
, p. 2173 - 2186 (2007/10/03)
The synthesis and directed dihydroxylation of a range of cyclic alkenes was investigated. Both homoallylic alcohols and homoallylic trihaloacetamides were found to be efficient directing groups, giving rise to good to excellent levels of remote asymmetric induction with OsO4-TMEDA. Interestingly, in all cases examined, trifluoroacetamides were found to be superior to trichloroacetamides as directing groups and an argument is presented which rationalises this observation.

REGIOSELECTIVE SYNTHESIS OF (+/-)-GABACULINE HYDROCHLORIDE
Frater, G.,Mueller, U.,Schoepfer, U.
, p. 281 - 284 (2007/10/02)
3-Cyclohexenecarboxylic acid (2) has been functionalized to the protected amino acid 5 in a novel reaction sequence, the crucial step being the acid catalysed cyclization of the γ,δ-unsaturated isocyanate 3 to the bicyclic lactam 4. 5 was converted into gabaculine hydrochloride (l HCl).
