A General Method for the Synthesis of 2-Alkyl Substituted 1,3-Dienes Starting from 2-(Chloromethyl)-3-tosylpropene
Najera, Carmen,Sansano, Jose Miguel
, p. 5829 - 5844 (2007/10/02)
The alkylation of the monolithium derivative 5 of 2-(chloromethyl)-3-tosylpropene (1) with bromo- or iodo-methyltrimethylsilane affords the β-silyl sulfone 7, which after nucleophilic substitution of the chlorine atom followed by β-elimination of tosyltrimethylsilane, promoted by tetrabutylammonium fluoride (TBAF), gives 2-substituted conjugated dienes 6 and the outer-ring diene 14.Racemic ipsenol (10b), an aggregation pheromone of the bark beetle Ips paraconfusus Lanier, is prepared.
2-(Chloromethyl)-3-tosylpropene as useful reagent for the general synthesis of functionalized 2-substituted 1,3-dienes. Application to the synthesis of (±)-ipsenol
Najera,Sansano
, p. 3781 - 3784 (2007/10/02)
The reaction of the monolithium derivative of 2-(chloromethyl)-3-tosylpropene (2) with bromomethyltrimethylsilane affords the β-silyl sulfone 7, which after nucleophilic substitution followed by fluoride induced β-elimination of tosyltrimethylsilane gives 2-substituted conjugated dienes 1. When compound 7 reacts first with zinc in the presence of isovaleraldehyde and then with tetrabutylammonium fluoride racemic ipsenol (10), an aggregation pheromone of the bark beetle Ips paraconfusus Lanier, is prepared.
A New Approach to the Formal Synthesis of (+/-)-α-Cedrene
Chen, Yao-Jung,Chen, Chew-Ming,Lin, Wen-Yuan
, p. 2961 - 2962 (2007/10/02)
A tandem radical cyclization, which proceeds via an addition/elimination mechanism, has been applied to the synthesis of norcedrenone 7, a precursor for the synthesis of (+/-)-α-cedrene 8.
3-Chloro-2-chloromethyl-4-(4-chlorophenoxy)-1-butene as a Functionalized Isoprene Unit. An Electrochemical Preparation and Some Reactions
Uneyama, Kenji,Hasegawa, Nobu,Kawafuchi, Hiroyuki,Torii, Sigeru
, p. 1214 - 1218 (2007/10/02)
3-Chloro-2-chloromethyl-4-(4-chlorophenoxy)-1-butene (1) was prepared in 72percent yield by electrooxidative double ene-type chlorination of 1-(4-chlorophenoxy)-3-methyl-2-butene.The electrolysis was conducted at room temperature in a two layer solvent sy
Stereoselective Synthesis of Racemic Trichodiene
Schlessinger, R. H.,Schultz, J. A.
, p. 407 - 408 (2007/10/02)
Lewis acid induced combination of 2--1,3-butadiene (8) and the α-methylene lactone 4 stereoselectively yields the adduct 9 which was converted into the sesquiterpene hydrocarbon trichodiene (1).
