• Baylis–Hillman adducts in rhodium-catalyzed 1,4-additions: unusual reactivity

  日期：——

  In the presence of a rhodium catalyst, unactivated Baylis–Hillman adducts reacted with arylboronic acids to afford trisubstituted alkenes with good yields. This highly efficient reaction (aerobic conditions, low temperature) is believed to proceeds via an unexpected mechanism involving 1,4-addition/β-hydroxy elimination steps and not π-allyl type rhodium intermediates.

  在铑催化剂的作用下，未活化的 BaylisâHillman 加合物与芳基硼酸发生反应，生成三取代烯烃，且收率很高。这种高效反应（有氧条件、低温）被认为是通过一种意想不到的机制进行的，其中涉及 1,4-加成/δ-羟基消除步骤，而不是Ï-烯丙基型铑中间体。

  [GRAPHICS]For R-2 = CN, Z-isomer (99%) was obtained.Treatment of fluorapatite (prepared by incorporating basic species F- in apatite in situ by coprecipitation) with an aqueous solution of RhCl3 resulted in rhodium-exchanged fluorapatite catalyst (RhFAP), which successfully promoted cross coupling of Baylis-Hillman adducts with arylboronic acids to yield trisubstituted olefins. A variety of arylboronic acids and Baylis-Hillman adducts were converted to the corresponding trisubstituted olefins, demonstrating the versatility of the reaction. The reaction is highly stereoselective. RhFAP was recovered quantitatively by simple filtration and reused with almost consistent activity.

  Efficient and general conditions for the formation of stereodefined trisubstituted alkenes by using the rhodium‐catalyzed reaction of unactivated Baylis–Hillman adducts with either organoboronic acids or potassium trifluoro(organo)borates are reported (see scheme).
