Kamlar, Martin; Franc, Michael; Cisarova, Ivana; Gyepes, Robert; Vesely, Jan published the artcile< Formal [3+2] cycloaddition of vinylcyclopropane azlactones to enals using synergistic catalysis>, Application of C9H7BrO, the main research area is spirocyclic azlactone enantioselective preparation; enal vinylcyclopropane azlactone cyclization palladium complex chiral amine catalyst.
Asym. cyclization of enals with vinylcyclopropane azlactones efficiently catalyzed by the combination of achiral Pd(0) complexes and chiral secondary amines was reported. Corresponding spirocyclic azlactones I [R1 = t-Bu, Ph; R2 = Et, Ph, 4-O2NC6H4, etc.; stereo = (5S,6S,7S,8R)/(5R,6S,7S,8R)] were produced in high yields with moderate diastereoselectivities and excellent enantioselectivities. This protocol provided an efficient and easily-performed route to spirocyclic scaffolds and densely functionalized cyclopentanes containing quaternary carbon centers.
Chemical Communications (Cambridge, United Kingdom) published new progress about [3+2] Cycloaddition reaction, stereoselective. 3893-18-3 belongs to class bromides-buliding-blocks, and the molecular formula is C9H7BrO, Application of C9H7BrO.
