Maripally, Narsimulu published the artcileDMAP catalyzed addition-cyclization reaction of 2-hydroxyphenyl-para-quinone methide with nitroalkenes: facile entry into highly substituted chromane derivatives, SDS of cas: 5153-73-1, the publication is Tetrahedron Letters (2020), 61(9), 151554, database is CAplus.
The base catalyzed reaction of 2-hydroxyphenyl-para-quinone methide (p-QM) with nitroalkenes was reported. The DMAP-catalyzed reaction afforded substituted chromane derivatives I [R = H, 7-Me, 6-MeO, 6-F, 6-Cl, 6-Br; R1 = i-Bu, Ph, 2-thienyl, etc.; stereo = R or S] in excellent yields with moderate diastereoselectivity. The conversion of the initial products to other useful structures was also achieved.
Tetrahedron Letters published new progress about 5153-73-1. 5153-73-1 belongs to nitriles-buliding-blocks, auxiliary class Nitrile,Alkenyl,Nitro Compound,Benzene, name is (E)-4-(2-Nitrovinyl)benzonitrile, and the molecular formula is C9H6N2O2, SDS of cas: 5153-73-1.
