✦ Synopsis

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 converted in one-pot into 3H-6-methoxypyrido[2,3,4-kl]acridine (15) by reaction with sodium [a]

## Abstract A new approach that tried to obviate the use of bromine protection groups was studied to synthesize (−)‐renieramycin G from L‐tyrosine. It was found that the first intermolecular Pictet–Spengler reaction proceeded successfully to give the correct tetrahydroisoquinoline precursor **6**.
