ChemInform Abstract: New Thermal and Photochemical Routes to Dewar Furan and Other Isomers on the C4H4O Energy Surface. The Role of Isobenzofuran as a Trapping Agent
Autor: I. G. Pitt, R. N. Warrener, R. A. Russell
Publikováno v: ChemInform. 22
Photolysis of the specially synthesized substrate (39) leads to quantitative fragmentation into the phthalimide (56) and Dewar furan (4a). Dewar furan has only transient existence even at -65°, yet can be trapped effectively with isobenzofuran but n

ChemInform Abstract: The Synthesis of Polarofacial Spacer Molecules: A New Twist in the Coupling of Ring Strained Olefins with Oxadiazoles
Autor: Wen Yan Liao, Douglas N. Butler, R. N. Warrener, I. G. Pitt, R. A. Russell
Publikováno v: ChemInform. 23
New approaches to the synthesis of rigid spacer molecules in which an oxygen-bridge bestows the facial polarity is described: attempts to couple 7-oxanorbornenes together using 1,3,4-oxadiazoles yields inverted, non linear products in a stereospecifi

ChemInform Abstract: Towards the Synthesis of a Dewar Furan Stabilized by a Pinching Group. The Role of Dewar o-Xylylenes as Dienes and Dienophiles
Autor: I. G. Pitt, R. A. Russell, R. N. Warrener
Publikováno v: ChemInform. 22
The synthesis of a photosubstrate (42) suitable for the production of a Dewar furan (46) containing a four-carbon bridge at the 1,4-position is described. The route to this product illustrates an example of transfer technology in synthesis, by using

ChemInform Abstract: The Synthesis of Spacer Molecules Containing an Alcohol Group at Each Terminus
Autor: Paul W. Groundwater, R. A. Russell, I. G. Pitt, R. N. Warrener, Douglas N. Butler
Publikováno v: ChemInform. 23
New spacer molecules are reported which contain alcohol functional groups at each end of the rigid carbocyclic framework. Simple coupling and extension reactions are used in their production thereby offering wide versatility in the shape, length and

ChemInform Abstract: Anodic Oxidation Products of 2′,5′-Dimethoxyacetanilide Derivatives, and Their Application to the Synthesis of Aminoanthraquinones
Autor: R. N. Warrener, R. W. Longmore, Richard A. Russell
Publikováno v: ChemInform. 23
Anodic oxidation of simple 2′,5′-dimethoxyacetanilides proceeds under mildly basic conditions to afford either monomeric or dimeric quinone bisacetals, depending on the structure of the substrate. Similarly, the oxidation of linked derivatives of
