3-dimethylenebornane (4b), (−)-borno[2,3-c]-2,5-diphenylcyclopenta-2,4-dien-1-one (9a), and related compounds are reported. A significant role is attributed to substituent chirality effects in these comparatively rigid, essentially planar cisoid conjugated diene systems.
(+)-5α-雄甾烯-14,16-二烯(2),(-)-冰片酚[2,3 - b ]环戊-1,3-二烯(3),(+)-报道了2,3-二亚甲基冰片烷(4b),(-)-冰片[2,3 - c ] -2,5-二苯基环戊-2,4-二烯-1-酮(9a)以及相关化合物。在这些相对刚性的,基本上为平面的类固醇共轭二烯体系中,取代基的手性效应起着重要作用。
