C-C bond-forming carboxylation and cyclization of trimethyl(2-methylenebut-3-yn-1-yl)silane derivatives and carbon dioxide was developed. Silver catalysts and CsF promoted the reaction to afford the corresponding 2-furanone and 2-pyrone derivatives in goo

supporting information; experimental part, p. 1023 - 1026 (2009/07/18)
The first catalytic method for the cyclization of vinyl-cyclopropyl ketones (formal homo-Nazarov reaction) is reported. Starting from activated cyclopropanes, heterocyclic, and carbocyclic compounds were obtained under mild conditions using Bronsted acid catalysts. Preliminary investigation of the reaction mechanism indicated a stepwise process.
New observations in organozinc chemistry: Control of relative stereochemistry in reactions of silicon substituted alkenylzinc reagents
Viseux,Parsons,Pavey
, p. 861 - 863 (2007/10/03)
Reagents have been synthesised that behave as both Lewis acids and nucleophiles. Reaction of these reagents with electrophiles has led to the finding that diastereoselectivity is observed upon addition to aldehydes. An ordered transition state to account
A Novel Synthesis of Transient 1,2-Cyclohexa-diene and 1,2-Cycloheptadiene via β-Halosilanes
Sutbeyaz, Yasar,Ceylan, Mustafa,Secen, Hasan
, p. 2189 - 2196 (2007/10/02)
A new method was developed to synthesize transient 1,2-cyclohexadiene and 1,2-cycloheptadiene.Fluoride ion-promoted elimination of 4 and 11 gave strained cyclic allenes 5 and 12, where 14 failed to react.
Simple method for controlling stereoselection in Mannich cyclization reactions of aldehydes
Heerding,Hong,Kado,Look,Overman
, p. 6947 - 6948 (2007/10/02)
By judicious choice of the nitrogen substituent, either stereoisomer of 1-substituted 1,2,3,4,6,7,8,8a-octahydroisoquinolines can be prepared by reactions of allylsilane amines 3 with aldehydes.
SILICON-DIRECTED NAZAROV CYCLIZATIONS VII. LINEARLY-FUSED TRICYCLICS
Denmark, Scott E.,Klix, Russell C.
, p. 4043 - 4060 (2007/10/02)
A new modification of the silicon-directed Nazarov cyclization is desribed wich involves the cyclization of divinyl ketones incorporating an allylsilane as the controll unit.The cyclisation are extremely facile with FeCl3 or BF3*OEt2 as the Lewis acid.Fou
