In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis of Nitrogen-Containing Heterocycles and Cyclopentenone Derivatives via Phosphine-Catalyzed Michael Addition/Intramolecular Wittig Reaction, published in 2017, which mentions a compound: 707-61-9, mainly applied to diketone cyclocondensation acetylenedicarboxylate phosphine catalyst; pyrrolizidine pyrroline pyridine cyclopentenone preparation; acetylenedicarboxylate amino carbaldehyde ester Michael addition intramol Wittig, SDS of cas: 707-61-9.
The phosphine-catalyzed Michael addition/intramol. Wittig reaction between dialkyl acetylenedicarboxylate and amino carboxaldehyde or amino ester has been developed. This reaction can be rendered catalytic in phosphine by the in situ chemoselective reduction of the phosphine oxide with a silane. This methodol. enables rapid access to a variety of nitrogen-containing heterocycles, which are present in numerous natural products and/or bioactive compounds Either classical heating or microwave conditions give access to the desired products in good yields (15 examples, 60-99% yields). This catalytic methodol. is further applicable to the synthesis of enantioenriched 1H-pyrrole derivatives, with the use of chiral phosphines. Finally, the reaction is extended to the synthesis of a polysubstituted cyclopentenone, starting from butane-2,3-dione as substrate.
After consulting a lot of data, we found that this compound(707-61-9)SDS of cas: 707-61-9 can be used in many types of reactions. And in most cases, this compound has more advantages.
