複素環(huán)式化合物

複素環(huán)式化合物は炭素原子と非炭素原子により構(gòu)成される環(huán)狀構(gòu)造の化合物である。これらの非炭素原子はヘテロ原子と総稱され，一般的なヘテロ原子は窒素、酸素、硫黃等である。前述したラクトン、ラクタム、環(huán)狀エーテル等の化合物はいずれも複素環(huán)式化合物であり，しかしこれらの化合物の性質(zhì)は同じ種類の鎖式化合物と類似するため，いずれも対応する章節(jié)に組み込んで説明する。本章は主に環(huán)構(gòu)造が穏やかで、ある程度の芳香族性を有する複素環(huán)式化合物，即ち芳香族複素環(huán)式化合物を説明する。複素環(huán)式化合物は種類が膨大であり，數(shù)量が多く，自然界に広く分布しており，多くの天然の複素環(huán)式化合物は動物、植物の體內(nèi)で重要な生理學(xué)的作用を果たす。例えば：植物內(nèi)のクロロフィル、動物の血中ヘモグロビン、漢方薬中の有効成分のアルカロイドと一部の配糖體、一部の抗生物質(zhì)とビタミン、タンパク質(zhì)のあるアミノ酸とヌクレオチドを構(gòu)成する塩基等はいずれも複素環(huán)構(gòu)造を含有する。従來の薬物中で、複素環(huán)構(gòu)造を含有するものは約半分を占める。そのため，複素環(huán)式化合物は有機化合物（特に有機薬物）中で重要な地位を占める。複素環(huán)式化合物中で五員、六員複素環(huán)及びそれらの縮合複素環(huán)化合物は最も普及しており，かつ最も重要である。そのため環(huán)のサイズによって，複素環(huán)式化合物は五員複素環(huán)及び六員複素環(huán)という二つの種類に分けられる。例えば上記フラン、チオフェン、ピロール、オキサゾール、イミダゾール及びそれらの縮合複素環(huán)化合物のインドール、ベンゾイミダゾール、ジベンゾフラン等はいずれも五員複素環(huán)式化合物であり，それに対してピリジン、ピリミジン及びそれらの縮合複素環(huán)化合物のキノリン、キナゾリン等はいずれも六員複素環(huán)式化合物である。各五員複素環(huán)式化合物と六員複素環(huán)式化合物中で，環(huán)構(gòu)造中のヘテロ原子の數(shù)量によって，また一つのヘテロ原子を含有する複素環(huán)及び二つ又はそれ以上のヘテロ原子を含有する複素環(huán)に分けられる。例えばフラン、チオフェン、ピリジン、インドール、キノリン、ジベンゾフラン等は一つのヘテロ原子を含有する複素環(huán)式化合物である；イミダゾール、ピリミジン、ベンゾイミダゾール、キナゾリン等は二つのヘテロ原子を含有する複素環(huán)式化合物である；それに対してプリンは二つ以上のヘテロ原子を含有するため，即ち複數(shù)のヘテロ原子を含有する複素環(huán)式化合物である。分子中の環(huán)構(gòu)造の形式によって，複素環(huán)式化合物はさらに複素単環(huán)及び縮合複素環(huán)という二つの種類に分けられる。例えばフラン、ピリジン、ピリミジン、イミダゾール等はいずれも複素単環(huán)式化合物であり，インドール、キノリン、ジベンゾフラン、プリン等は縮合複素環(huán)式化合物である。
