scheme or table, p. 1349 - 1352 (2012/07/14)
A convenient route to an original chiral sulfonic acid is disclosed. The synthesis is based on an optimized and regioselective direct bis-orthoarylation of a commercially available phenol, followed by a Newman-Kwart rearrangement. Resolution by preparative chiral HPLC and oxidative cleavage give the targeted Brnsted acid in >99% ee. Georg Thieme Verlag Stuttgart · New York.
Restricted Rotation Involving the Tetrahedron Carbon. XLIII. Buttressing Effect on Rotational Barriers in Bromine-substituted 9-(2-Methoxy-4,6-dimethylphenyl)fluorenes

, p. 2512 - 2515 (2007/10/02)
9-(2-Methoxy-4,6-dimethylphenyl)fluorenes carrying one or two bromo groups on the phenyl ring were prepared and the buttressing effect on the rotational barrier about the C9-Cph bond were investigated.The free energies of activation
