چکیده
A novel cyclization process of 2,3-bis(trimethylsilyl)buta-1,3-diene with various acyl chlorides in the presence of aluminium trichloride affords 2,5-disubstituted or 2,3,5-trisubstituted furans in short reaction time; a subsequent acylation process of the furan ring occurs if the reaction time is prolonged.

4-Acyl-1-hydroxy-2,3-benzodioates were regioselectively prepared by chelation-controlled [3+3] cyclization of 1,3-bis(trimethylsilyloxy)-1,3-butadienes with 3-acyl-4-ethoxy-2-oxo-3-enoates.
متن کاملA conjugate addition/dipolar-cycloaddition cascade sequence for the synthesis of ()-cylindricine C
An efficient stereocontrolled route to ( )-cylindricine C is described. Reaction of 9-hydroxynon-1-en-5one oxime with 2,3-bis(phenylsulfonyl)-1,3-butadiene affords a 7-oxa-1-azanorbornane cycloadduct in high yield. The formation of the bicyclic isoxazolidine arises from conjugate addition of the oxime onto the diene to give a transient nitrone that spontaneously undergoes an intramolecular dipo...
متن کاملAn ab initio/RRKM study of product branching ratios in the photodissociation of buta-1,2- and -1,3-dienes and but-2-yne at 193 nm.
Ab initio G2M(MP2)//B3LYP/6-311G** calculations have been performed to investigate the reaction mechanism of photodissociation of buta-1,2- and -1,3-dienes and but-2-yne after their internal conversion into the vibrationally hot ground electronic state. The detailed study of the potential-energy surface was followed by microcanonical RRKM calculations of energy-dependent rate constants for indi...
متن کامل2,3-Bis(phenoxymethyl)buta-1,3-diene
The mol-ecule of the title compound, C(18)H(18)O(2), a symmetrically phenol-substituted divinyl analog, exhibits crystallographically imposed C(2) symmetry. The phenolic and divinyl planar groups inter-sect each other orthogonally, with a dihedral angle of 82.7 (1)°. The structure is stabilized by a short intra-molecular C-H⋯O contact. The mol-ecules are held together by C-H⋯π inter-actions, fo...
متن کاملA novel 3,4-bis(sulfenyl)- or 4-selenenyl-3-sulfenylpenta-2,4-dienylation of aldehydes using 4-ethoxy-1,2-bis(sulfenyl)- or 1-Selenenyl-2-sulfenyl-buta-1,3-dienyl lithiums.
3,4-Dichalcogenopenta-2,4-dienylation of aldehydes proceeded in good to high yields using 4-ethoxy-1-(benzenesulfenyl)-2-(methanesulfenyl)- (5), 4-ethoxy-1,2-bis(benzenesulfenyl)but-1,3-diene (6), and 1-selenenyl derivatives 7 and 8. This novel four-carbon homologation could be applied to a synthesis of 3,4,7,8-tetrakis(benzenesulfenyl)-10,10-dimethylundeca-2,4,6,8-tetraenal (20).
