• Nickel/Photo-Cocatalyzed C(sp²)–H Allylation of Aldehydes and Formamides
  作者：Pei Fan、Rui Wang、Chuan Wang

  DOI：10.1021/acs.orglett.1c02938

  日期：2021.10.1

  nickel/photo-cocatalyzed C(sp2)–H allylation of aldehydes and formamides wherein both allyl acetates and allyl alcohols can be used as the allylating agents. In this reaction, radical-type umpolung of the formyl moiety is enabled by tetrabutylammonium decatungstate as a hydrogen-atom-transfer photocatalyst, whereas nickel serves to cleave the C–O bond of allyl acetates or allyl alcohols. The synergistic effect

  在此，我们报告了一种镍/光共催化的醛和甲酰胺的C(sp 2 )-H 烯丙基化，其中乙酸烯丙酯和烯丙醇均可用作烯丙基化剂。在该反应中，四丁基十钨酸铵作为氢原子转移光催化剂实现了甲酰基部分的自由基型聚合，而镍则用于裂解乙酸烯丙酯或烯丙醇的 C-O 键。这两种催化剂的协同作用为获得各种具有高选择性的 β,γ-不饱和酮和酰胺提供了新的途径。

  Amidyl radicals generated from tributylstannane mediated homolysis of O-benzoyl hydroxamic acid derivatives (2a-d) undergo 4-exo trig cyclisation to furnish β-lactam derivatives (4a-d).

• Aza- and oxacarbonylations of allyl phosphates catalyzed by rhodium carbonyl cluster. Selective synthesis of β, γ-unsaturated amides, esters, and acids

  日期：1993.6

  Rhodium-catalyzed carbonylation of allyl phosphates under CO (20 atm) at 50°C proceeds very efficiently in the presence of amines, alcohols, and water to give the corresponding β,γ-unsaturated amides, esters, and acids, respectively. These carbonylations occur with high regioselectivity at the less substituted carbon of allyl unit to give linear β,γ-unsaturated acid derivatives.

  在胺，醇和水的存在下，在50°C的CO（20 atm）下铑的烯丙基磷酸酯的羰基催化羰基化反应非常有效，分别得到相应的β，γ-不饱和酰胺，酯和酸。这些羰基化在烯丙基单元的较少取代的碳上以较高的区域选择性发生，从而得到线性的β，γ-不饱和酸衍生物。

  The present application relates to a compound having a formula 1: B—R1-R2-M wherein B is a binding element for recognizing and binding a target; R1 is a first group of atoms for reacting with a functionality of the target so as to form a covalent bond with the target; R2 is a second group of atoms; R1 and R2 being such that the formation of the covalent bond between R1 and the target generates cleavage of the bond between R1 and R2 so as to free R2-M; and M is selected from the group consisting of a hydrogen atom and a pharmaceutically acceptable moiety. Alternatively, R1 and R2 can be inverted to form the formula II: B—R2-R1-M and being such that the formation of the covalent bond between R1 and the target generates cleavage of the bond between R1 and R2 so as to free R2-B.
