, p. 5574 - 5575 (1993)
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
Synthesis of Functionalized 1-Silyl-substituted Dienes by Regioselective Cyclopropanation of 1-Silyl-substituted Butadienes with Dibromocarbene Followed by AgI-Promoted Ring-opening of the resulting Dibromocyclopropanes

, p. 2687 - 2692 (2007/10/02)
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
