substituents have been synthesized as potential bioreduetive alkylating agents. The method presented here involves the syntheses of 1,4-dimethoxybenzalkehydes or 1,4-dimethoxynaphthaldehydes, and conversion of the carbonyl groups into the oxiranyl function using trimethylsulfonium chloride in the presence of powdered sodium hydroxide 1,4-Dimethoxy-2-oxiranyl-benzenes and 1,4-dimethoxy-2-oxiranylnaphthalenes

2-(2-chloro-4-pyridyl)-4,4-dimethyl-4,5-dihydro-oxazole and subsequent condensation with aromatic aldehydes provides a four-step synthesis of both 1-chloro-2-aza-anthraquinone and 1-chloro-2-azanaphthancenequinone derivatives which are keyintermediates in the preparation of mitoxanthrone analogues.
In this study, a formal synthesis of isoquinocyclinone is reported. Synthesis of key intermediate lactone 6, an intermediate in Koert's s totalsynthesis of isoquinocyclinone, was succeeded. The lactone 6 was synthesized by using our developed diazo-transfer reaction of anthranol with 2-azido-1,3-dimethylimidazolinium chloride (ADMC) and alkoxycarbonylmethylation of diazoquinone as key reactions.
