Catalytic asymmetric torgov cyclization: A concise total synthesis of (+)-estrone

An asymmetric Torgov cyclization, catalyzed by a novel, highly Bronsted acidic dinitro-substituted disulfonimide, is described. The reaction delivers the Torgov diene and various analogues with excellent yields and enantioselectivity. This method was applied in a very short synthesis of (+)-estrone.

Synthesis of Isomeric exo- and endo-Bicyclooctane-6,8-dione Derivatives by Acid-catalysed Cyclization Reaction

2-Methyl-2-(3'-aryl-3'-alkylprop-2'-enyl)cyclopentane-1,3-diones (seco-diones, 2a-e and g) have been synthesised from the corresponding ketones (1a-e and g) by the Torgov's method.A conveniant and general synthesis of the title compounds (3a-g and 4a-g) r
