摘要:Abstract(#br)This work describes the study of behavior of the δ-substituted and δ-non-substituted exo -cyclic double bond of γ-alkylidenebutenolides with dialkylcuprates. The addition reaction was found to be regioselective to afford the 1,6-conjugate adduct up to 87% yield.

摘要:Abstract(#br)Synthesis of butenolides or α-pyrones from substituted tributylstannyl acetylides is highly dependant on the nature of the acetylide.

摘要:Abstract(#br)The convergent synthesis in high enantiomeric and diastereoisomeric purity of (11 R ,17 S )-11,17-dimethylhentriacontane, a communication pheromone of ant Camponotus vagus is described. The stereogenic centres were introduced from commercially available ( R )-citrone...

摘要:Abstract(#br)Tributylstannyl-( Z )-3-tributylstannyl-4-trimethylsilylbut-3-enoate is prepared by the stereospecific addition of (tributylstannyl)-trimethylsilane on the but-3-ynoic acid. Some of the potentialities of this synthon are established through cross-coupling and reverse...

摘要:Abstract(#br)α-Tributylstannylacetals derived from chiral C 2 symmetry axis diols were reacted with miscellaneous organometallic reagents to give chiral α-oxygenated organotins in high yields. The Lewis acid promoted ring opening of the these chiral α-tributylstannylacetals ...

摘要:Abstract(#br)Stereoselective construction of ethyl (13 E )-trifluoromethylretinoate was achieved through two successive Stille reactions. The coupling of ( E )-1,2-bis(tributylstannyl)ethene and ethyl ( Z )-4,4,4-trifluoro-3-iodobut-2-enoate was performed first and followed ...

摘要:Abstract(#br)C 5 -branched vinyltin acetals 1 and 2 obtained by stannylmetallation of homopropargyl acetals with Bu 3 SnMgMe in the presence of cuprous cyanide have been proved to be efficient storable precursors for the synthesis of terpenoids.

摘要:Abstract(#br)The cross talk between different membrane receptors is the source of increasing research. We designed and synthesized a new hetero-bivalent ligand that has antagonist properties on both A 1 adenosine and μ opiate receptors with a K i of 0.8 ± 0.05 and 0.7 ± 0.03...

摘要:Abstract(#br)The first total synthesis of both enantiomers of furocaulerpin was accomplished in good yields with a high control of the stereogenic center by enzymatic resolution, a total control of the configuration of the central double bond and the construction of the dienyne m...
