A new tandem CN and CC bond‐forming reaction has been achieved through RhII/Pd0 catalysis. The sequence first involves an iodine(III) oxidant, then the in situ generated iodine(I) by‐product is used as a coupling partner. The overall process demonstrates the synthetic value of iodoarenes produced in trivalent iodine reagent mediated oxidations.
通过Rh II / Pd 0催化实现了一个新的串联CN和CC键形成反应。该序列首先涉及碘(III)氧化剂,然后将原位生成的碘(I)副产物用作偶联伴侣。整个过程证明了在三价碘试剂介导的氧化反应中产生的碘代芳烃的合成价值。
Combination of gold and redox enzyme catalysis to access valuable enantioenriched aliphatic β-chlorohydrins
The synthesis of enantioenriched β-chlorohydrins is highly appealing due to their relevance as building-blocks in organicsynthesis. However, the approximation to aliphatic derivatives is particularly challenging due to the difficulties to get access to the α-chloroketone precursors. Herein, we propose a straightforward and scalable approach combining in a concurrent manner gold(I) and redox enzyme
