4,4-Dimethyl Effect. (3). The Ring A Conformation of 4,4-Dimethyl-Δ^7-3-keto Steroids and 4,4,8-β-Trimethyl-3-keto Steroids (3-Keto-triterpenoids). The Crystal Structure of Serratenedione

概要
- 論文の詳細を見る
Single crystals of serratenedione grown in methanol are orthorhombic, a=14.506,b=10.558,c=16.296 Å, U=2495.8 Å^3,D_c=1.17 g/cm^3,Z=4,with space group P2_12_12_1. The structure, solved by use of the MULTAN program, revealed the conformation of the compound to be as follows : ring A, deformed boat ; B, chair ; C, chair-like ; D, half-chair ; and E, distorted chair. Circular dichroism (CD) spectra of 4,4-dimethyl-3-keto steroids with Δ^7 or an 8β-methyl group are discussed in connection with the above results.
