## Abstract Antheridiol‐(22,23‐^3^H) has been prepared by reduction of 3‐acetoxy‐23,23‐dihydroxy‐22‐oxo‐5, 24(28)‐ergostadiene‐28‐carboxylic acid gamma ‐ lactone with tritiated sodium borohydride followed by hydrolysis, photo‐oxygenation and cupric chloride catalysed rearrangement.
## 9H-quino[4,3,2-de][1,10] phenanthrolin-9one) (1) and an isomer (9H-quino[4,3,2-de][1,7]phenanthrolin-9-one) (4) have been synthesized starting from 1,4-dimethoxyacridone (7). The acridone was converted into 1,4-dimethoxy-9-ethynylacridine ( 11) by a triflate coupling. The ethynylacridine was co
