α-phenylseleno ketones has been developed, making use of the lithium naphthalenide induced reductive selenenylation of the α-cyano ketone system as a key operation. Moreover, seleno ketones thus generated in situ, upon subsequent treatment with hydrogen peroxide and acetic acid, could be further converted into the corresponding enones with a high degree of regioselectivity, presumably due to the lithium salt
利用萘基锂诱导的α-氰基酮系统的还原硒基化作为关键操作,已经开发了一种用于区域控制合成α-苯基硒酮的有效程序。此外,如此原位生成的硒酮,在随后用过氧化氢和乙酸处理后,可以以高度的区域选择性进一步转化为相应的烯酮,这可能是由于锂盐介导的硒氧化物同步消除过程。
