标 题:Synthesis of 13-alkyl-gon-4-ones

摘要:The preparation of 13-methylgon-4-enes and novel 13-polycarbonalkylgon-4-enes by a new total synthesis is described. 13-Alkylgon-4-enes having progestational, anabolic and androgenic activities are prepared by forming a tetracylic gonane structure unsaturated in the 1,3,5(10),9(11) and 14-positions, selectively reducing in the B- and C-rings, and converting the aromatic A-ring compounds so-produced to gon-4-enes by Birch reduction and hydrolysis.

摘要:THE COMPOUND 2,4,6-TRI-T-BUTYL-4-METHOXYCYCLOHEXA2,5-DIEN-1-ONE, HAVING THE FOLLOWING STRUCTURAL FORMULA 1,3,5-TRI(T-C4H9-),5-(CH3-O-)CYCLOHEXA-2,5-DIEN-1-ONE IS SYNTHESIZED IN ONE STEP BY REACTING 2,4,6-TRI-T-BUTYLPHENOL, BROMINE, METHANOL AND AN ALKALI METAL CARBONATE AT A TEMPERATURE WITHIN THE RANGE 20 TO 80*C. THE PRODUCT COMPOUND HAVING THE ABOVE FORMULA IS PRODUCED IN 65 PERCENT OR BETTER YIELD. IT IS USEFUL AS AN INTERMEDIATE IN THE PREPARATION OF 2,6-DI-T-BUTYL-4-METHOXYPHENOL OR 2-T-BUTYL-4-METHOXYPHENOL, BOTH OF WHICH ARE USEFUL AS ANTIOXIDANTS, THE FORMER IN NON-FOOD USES AND THE LATTER IN FOODS.
