synthesis of chalcones and flavanones has been described. 2-(Benzo[d]thiazol-2-ylsulfonyl)-1-phenylethanones have been developed as new reagents for direct Julia–Kocienski olefination with aldehydes in the presence of a base, afforded chalcones in good to excellent yields. Whereas, 2-(benzo[d]thiazol-2-ylsulfonyl)-1-(2-hydroxyphenyl)ethanone reacted with the aromatic aldehydes to furnish flavanones
已经描述了朱莉娅-科辛斯基烯烃合成在查耳酮和黄烷酮合成中的新应用。2-(苯并[ d ]噻唑-2-基磺酰基)-1-苯乙酮已被开发为用于直接朱莉娅- Kocienski烯新试剂在碱的存在下的醛,得到良好的查耳酮以优良的产率。而2-(苯并[ d ]噻唑-2-基磺酰基)-1-(2-羟基苯基)乙酮与芳族醛反应,通过一锅内分子内环化反应以高收率提供黄烷酮。
