Intramolecular ene reaction of 1,6-fullerenynes: a new synthesis of allenes.
نویسندگان
چکیده
[Structure: see text] Thermal treatment of 1,6-fullerenynes bearing an alkyl group on the terminal carbon of the alkyne moiety leads quantitatively to new allenes through a reaction mechanism involving an intramolecular ene process. This reaction outcome is in contrast to that recently found for free terminal alkynes which form cyclobutene derivatives through a [2+2] cyclization mechanism.

Theoretical study of the reaction mechanisms involved in the thermal intramolecular reactions of 1,6-fullerenynes.
Substitution of a H atom by an alkyl group on the terminal carbon of the alkyne moiety of 1,6-fullerenynes has a strong impact on the products of the reaction undergone by this species after thermal treatment. While the reaction of 1,6-fullerenynes bearing an unsubstituted alkyne moiety results in the cycloaddition of the alkyne group to the fullerene double bond leading to cyclobutene-fused de...
متن کاملHighly regio- and chemoselective [2 + 2 + 2] cycloaddition of 1,6-heptadiynes with allenes catalyzed by cobalt complexes.
The CoI2(PPh3)2/Zn system effectively catalyzes the [2 + 2 + 2] ene-diyne cycloaddition of 1,6-heptadiynes with allenes in a highly regio- and chemoselective fashion to yield substituted benzene derivatives in good to excellent yields.
متن کاملEnantioselective desymmetrization of cyclohexadienones via an intramolecular Rauhut–Currier reaction of allenoates
The Rauhut-Currier (RC) reaction represents an efficient method for the construction of carbon-carbon bond in organic synthesis. However, the RC reactions involving allenoate substrates are very rare, and in particular, asymmetric intramolecular RC reaction of allenoates is yet to be discovered. Here, we show that the intramolecular RC reaction proceeds smoothly in the presence of 1 mol% β-ICD,...
متن کاملOne-Pot Synthesis of Some New α-Bromoketals and Acetals via 1,8-Diazabicyclo[5.4.0] Undec-7-ene-Hydrobromide-Perbromide
α-Bromoketals and acetals are important synthetic precursors in organic synthesis. In this work, some new α-bromoketals are synthesized by the reaction of aryl methyl ketones with diols in the presence of 1,8-diazabicyclo[5.4.0] undec-7-ene (DBU) hydrobromide-perbromide in good isolated yields. The latter compound converts aldehydes to acetals and serves as a new and efficient reagent for t...
متن کاملCobalt-mediated cyclotrimerization and cyclo- isomerization reactions. Synthetic applications*
This article reviews our contribution in the ®eld of the cobalt(I)-mediated cyclizations. The use of new unsaturated partners such as allenes extend the scope and the utility of the previously developed intramolecular [222] cyclotrimerization. The presence of chiral auxiliaries induced high level of diastereoselectivity in the enediynes cyclization. The discovery of cobalt(I) catalyzed ene-ty...
