New Approach to the Steroid BCD-Ring System Using Tandem Radical Cyclization was written by Takahashi, Takashi;Tomida, Satoshi;Sakamoto, Yasuharu;Yamada, Haruo. And the article was included in Journal of Organic Chemistry in 1997.COA of Formula: C12H18O3 The following contents are mentioned in the article:
An efficient synthesis of the steroid BCD-ring system has been accomplished via tandem radical cyclization of the acyclic iodide derivative I. This tandem radical cyclization allows for the formation of the steroid CD ring having the requisite trans stereochem. between the C-13 Me and C-14 hydrogen as well as diequatorial substituents at C-8 and C-9. The stereoselectivity of the radical cyclization was successfully predicted on the basis of modeling of the transition state structure. This study involved multiple reactions and reactants, such as (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5COA of Formula: C12H18O3).
(2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.COA of Formula: C12H18O3
