The reaction of 1-trimethylsilyl-substituted butadienes with dibromocarbene, generated from CHBr3 and KOH under phase-transfer conditions gave, regioselectively, the corresponding cyclopropane adduct.The ring formation occurs at the double bond away from
Tandem Radical Cycloaddition. Remarkable Silyl Substituent Effect on the Chemoselectivity of the Radical Cyclization Reactions

Tandem radical cyclization of bromides 1 with Bu3SnH is extremely sensitive to the nature of the substituent on the diene moiety.Bicyclo skeleton 3 is obtained in the presence of the silyl substituent.The tert-butyl substituent gives exclusively si
