With a part of research for development of fresh marine notes in algae, following research results were obtained. A novel heme protein, which catalyzes oxygenation of polyunsaturated fatty acids affording oxylipins in Chapter I.Both enantiomers of neodictyoprolene and neodictyoprolenol reminiscent of algae, were successfully obtained by chemo-enzymatic syntheses, and their attractive olfactory properties were found in Chapter II.The biosynthetic intermediates of characteristic long-chain aldehydes were identified as (2R)-hydrperoxy fatty acids in green algae in Chapter III.The (Z)-unsaturated dienenals and trienals of CィイD217ィエD2 and CィイD216ィエD2 were stereoselectively synthesized and their olfactory evaluation showed a variety of applications in perfume industry in Chapter IV.

本论文通过对海藻中海洋鲜香成分开发的部分研究，取得了以下研究成果。在第一章中，一种新的血红素蛋白，它催化多不饱和脂肪酸的氧化，从而提供氧脂。通过化学-酶促合成，成功地获得了两种使人联想到藻类的对映体neodictyoprolene和neodictyoprolenol，第三章从绿色藻类中鉴定出特征性长链醛类的生物合成中间体为（2R）-过氧氢脂肪酸。（第四章立体选择性地合成了C_（217）C_（216）C_（217）D_2和C_（216）C_（216）D_2的（Z）-不饱和二烯醛和三烯醛，并对其在香料工业中的应用进行了评价。
