설명
1-Bromo-2-butyne is used in the preparation of six to eight annulated ring compounds in reaction with indoles and pseudopterane (±)-Kallolide B, which is a marine natural product. Further, it acts as a precursor in the preparation of axially chiral teranyl compounds, alkylation of L-tryptophan methyl ester, 4-butynyloxybenzene sulfonyl chloride and mono-propargylated diene derivative. In addition to this, it is also used in the synthesis of isopropylbut-2-ynylamine, allenylcyclobutanol derivatives, allyl-[4-(but-2-ynyloxy)phenyl]sulfane, allenylindium and axially chiral teranyl compounds.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
1-Bromo-2-butyne is used in the preparation of six to eight annulated ring compounds in reaction with indoles and pseudopterane (+/-)-Kallolide B, which is a marine natural product. Further, it acts as a precursor in the preparation of axially chiral teranyl compounds, alkylation of L-tryptophan methyl ester, 4-butynyloxybenzene sulfonyl chloride and mono-propargylated diene derivative. In addition to this, it is also used in the synthesis of isopropylbut-2-ynylamine, allenylcyclobutanol derivatives, allyl-[4-(but-2-ynyloxy)phenyl]sulfane, allenylindium and axially chiral teranyl compounds.
