| description | 6,9-Oxido-9,10-seco-1,3,5(10),6,8,14-estrahexaenes, useful as intermediates in the total synthesis of steroids, of the formula WHEREIN N IS 1 OR 2, R1 is lower-alkyl, R2, R 3 and R4 are H, alkoxy or acyloxy, X is a free or ketalized keto or free, esterified or etherified hydroxymethylene, are produced by the cyclization, with an acid catalyst, of a 9,10-secoestrane of the formula WHEREIN R1, R2, R3, R4, X and n have the values given above, and Q is carbonyl or dialkoxymethylene. Hydrogenation produces the corresponding 6,9-oxido-9,10-seco-1,3,5(10)-estratrienes and 9-oxy-9,10-seco-1,3,5(10)-estratrienes. |
