Research Abstract	交付申請書記載の各項目順に成果を記す。 1・〔3+2〕光付加によるアネレーション新たに、2-ヒドロキシ-ノ,4-フェナントレンキノンとフェニルアセチンの位置選択的光付加によりフェナントロ〔2,3-6〕フラン-4,11-ジオン滂導体の生成、2-メルカプトナフトキノンとアルケンの光付加によるヒドロナフト〔2,3-6)チオフエン-4,9-ジオン類の生成を見出した。 2・アルコキシルラジカルのベータ開製の有機合成への応用新たにフルコキシルラジカルのβ-開製をキーステップとして、非対称天然リグナンである(±)-メチルピペリトール、セスキテルペンである(±)カリオフィレン、(±)イソカリオフィレンを全合成した。また、同様の手法を用いてセスキテルペンであるα-ヒマチヤレンの骨格を合成した。アルコキシルラジカルの開製反応を用いて2-ヒドロキシテトラヒドロピランからアルキル置換ピロリジンを合成する新手法を開発した。 3・ステロイド系不飽和オキシムの光による分子内転位反応 β,γ体への光異性化、メタノールの二重結合への立体特異的光付加の機構を重水素標識化実験により解明した。 4・電極反応を用いる新規有機化学プロセスの開発反応性電極を用いる置換ハロゲン化プロパルギルと炭酸ガスの反応による電解カルボキシル化反応、電解調製活性亜鉛を用いるカルボニル化合物のイソプレニル反応等を開発した。 5・その他〔2+2〕光付加-ベータ開製による複業環の合成、不飽和アミンのアニオン的環化によるシス-2置換ピロリジンの合成法を開発した。
