A radical Smiles rearrangement strategy for allowing an unprecedented [3+2]/[3+2] carboannulation of dienynes 2-CCR3-R1C6H3N(R2)C(O)C(=CH2)CH=CH2 (R1 = H, 4-OMe, 4-Br, 5-F, etc.; R2 = Me, Bn; R3 = Ph, thiophen-2-yl, 4-chlorophenyl, etc.) with arylsulfonyl chlorides 2-R4-3-R5-4-R6C6H2S(O)2Cl (R4 = H, Me; R5 = H; R4R5 = -CH=CH-CH=CH-; R6 = H, OMe, Me, Cl, Br, I; R7 = H, 3-OMe, 3-Br, 2-F, etc.) using cheap copper catalysis was described. This cascade method represents a novel cycloaddition mode for dienyne chem., which occurs by the sequence of addition of arylsulfonyl radical to a dienyne, and a Smiles rearrangement and radical annulation to access cyclopenta[a]indene-fused quinolinones I with excellent diastereoselectivity. The experimental process involved the reaction of 4-Chlorobenzenesulfonyl chloride(cas: 98-60-2Related Products of 98-60-2)
4-Chlorobenzenesulfonyl chloride(cas: 98-60-2) belongs to organochlorine compounds. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Related Products of 98-60-2
