Booker-Milburn, Kevin I. published the artcileTandem ring expansion-cyclization reactions: a novel method for the rapid construction of the bicyclo[5.3.0]decane ring system, Recommanded Product: (4-Bromobut-1-yn-1-yl)trimethylsilane, the publication is Synlett (1992), 809-10, database is CAplus.
Treatment of the cyclopropyl silyl ether I with ferric chloride in DMF gave the 5,7-bicyclic chloro ketone II via a tandem free radical ring expansion-cyclization sequence. The acetylenic derivatives III (R = SiMe3, CO2Me) underwent the same expansion-cyclization sequence to yield similar 5,7-carbocycles.
Synlett published new progress about 69361-41-7. 69361-41-7 belongs to bromides-buliding-blocks, auxiliary class PROTAC Linker,Aliphatic Linker, name is (4-Bromobut-1-yn-1-yl)trimethylsilane, and the molecular formula is C7H13BrSi, Recommanded Product: (4-Bromobut-1-yn-1-yl)trimethylsilane.
