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 Enantioselective Organocatalytic Intramolecular Ring-Closing Friedel-Crafts-Type Alkylation of Indoles, published in 2007-05-10, which mentions a compound: 67929-86-6, mainly applied to indolyl unsaturated aldehyde imidazolidinone enantioselective intramol Friedel Crafts alkylation; indole tetrahydropyrano derivative stereoselective preparation; carboline tetrahydro derivative stereoselective preparation; enantioselective intramol Friedel Crafts alkylation organocatalyst chiral imidazolidinone; bromomethyltetrahydropyrano indolylethanol preparation crystal structure, SDS of cas: 67929-86-6.
An enantioselective organocatalytic intramol. ring-closing Friedel-Crafts-type alkylation of indolyl α,β-unsaturated aldehydes has been developed. This powerful new strategy allows enantioselective access to THPIs (tetrahydropyrano[3,4-b]indoles), e.g., I, and THBCs (tetrahydro-β-carbolines), e.g., II, in a straightforward and atom-economical manner.
There are many compounds similar to this compound(67929-86-6)SDS of cas: 67929-86-6. if you want to know more, you can check out my other articles. I hope it will help you，maybe you’ll find some useful information.
