Abstract
กระบวนการที่ดีขึ้นได้รับการอธิบายสำหรับการเตรียมไดไฮโดรเบนโซฟิวแรนที่ถูกแทนที่ ด้วย (โพรพีนิลที่ถูกแทนที่สองตำแหน่ง)เฟนิลแอลคิล กระบวนการที่ดีขึ้นนี้มุ่งเน้นขั้นตอนเพื่อผลิต สารระหว่างกลางสำคัญ กล่าวคือสารประกอบที่มีสูตร I (สูตรเคมี) I ซึ่ง R3, R4, R5, R6 และ x เป็นดังที่นิยามข้างต้น Improved processes are described for the preparation of substituted dihydrophenylsylic (propeneylsupplied) phenyl alkyl. This improved process focuses on the steps to produce. Important intermediate That is to say, compounds with formula I (chemical formula) I, where R3, R4, R5, R6 and x are defined above.
