摘要:已经开发了一种使用binol衍生物作为手性离去基团和路易斯酸的新策略,用于前手性烯烃的对映选择性烷基化.已证明(R)-2,2'-双[2-(三甲基甲硅烷基)乙氧基甲基]-1,1'-联苯酚是用于甲硅烷基烯醇醚和三取代烯烃的对映选择性羟甲基化的有效试剂.前手性烯烃的亲电加成伴随着乙缩醛的裂解,该缩醛被sncl4双重激活,并且硅通过s(n)2取代过程产生了δ效应.使用该策略还描述了环状萜烯的对映选择性合成.

标题:Synthesis of pseudopterosin compounds
发明人：COREY ELIAS J
权利人:HARVARD COLLEGE
摘要:The present invention is directed to a new synthetic route to pseudopterosin aglycone (3): n a key intermediate for the synthesis of a group of antiinflammatory natural products including pseudopterosin A (1) and E (2). The pathway of synthesis starts with the abundant and inexpensive (S)-(−)-limonene and its long-known cyclic hydroboration product (4) and leads to the chiral hydroxy ketone (6). Conversion of (6) to (10) followed by a novel aromatic annulation produced (15) which underwent highly diastereoselective cyclization to afford the protected pseudopterosin aglycone (16). The naturally occurring pseudopterosins such as (1) and (2) are readily available from this key intermediate.

发明人：CRAWFORD ROBERT J
权利人:PROCTER & GAMBLE
摘要:Disclosed herein is the synthesis of 4-(4-methylcyclohex-3-en-1yl)pent-4-en-1-ol, a novel compound useful as a starting reagent for the production of lanceol and lanceal, known perfume materials. Limonene is first metalated and then reacted with ethylene oxide to give the novel compound. This compound can then be converted to a known aldehyde which can be used to produce lanceol and lanceal by known processes.
