Cotterill, Ian C.,Roberts, Stanley M.
, p. 2585 - 2586 (2007/10/02)
The anti-herpes agent carbocyclic oxetanocin-A (-)-2 has been prepared from the bicyclic ketone 3 via resolution of the bromohydrin 4 (using an enzyme-catalysed trans-esterification reaction) and a photocatalysed rearrangement of the epoxide (+)-6 to the
Enzymatic Resolution of Sterically Demanding Bicycloheptanes: Evidence for a Novel Hydrolase in Crude Porcine Pancreatic Lipase and the Advantages of using Organic Media for Some of the Biotransformations

Sterically demanding 7,7-dimethylbicyclohept-2-en-6-one 1 was enzymatically resolved via the exo-acetate 11a using crude porcine pancreatic lipase.By employing different fractions of hydrolases from the crude enzyme, evidence was obtained that an e

Photolysis of 2,3-endo-epoxy-7,7-diphenylbicycloheptan-6-one ( 2 ) in methanol gave products ( 4 ), ( 8 ) derived from an oxacarbene intermediate and the products ( 5 ) - ( 7 ), ( 9 ) derived from an initially formed alkenylketene.Photolysis of the
Photochemical Conversion of 7,7-Diphenyl-2,3-epoxybicycloheptan-6-ones into a 2-Oxabicyclohexan-3-one

Photolysis of the epoxide (3) or (5) gave the strained lactone (4) in 40 - 50percent yield; the bicyclic lactone (4) gave the functionalised cyclobutane (6) on treatment with acidic methanol, the structure of which was confirmed by X-ray analysis.
