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)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)Using a double Suzuki cross-coupling reaction ortho - or para -bromobenzyl bromides are easily transformed into unsymmetrical diaryl (or heteroaryl) methanes

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)( E )- or ( Z )-perfluorinated β-enaminoesters were prepared by direct addition of primary or secondary amines to ethyl perfluoroalkynoates without any catalyst.

摘要:Abstract(#br)Stereoselective synthesis of rigid 9,10-didehydro retinoic acids was achieved from (2 Z or 2 E ,4 E )-5-iododienoic acids through a Heck–Sonogashira cross-coupling reaction.

摘要:Abstract(#br)( E )-Aryl or heteroarylvinylgermanes are obtained by Stille reactions using ( E )-1-tributylstannyl-2-trialkyl (or triphenyl) germylethylenes.

摘要:Abstract(#br)Stereoselective synthesis of vinylstannanes bearing a carboxylic acid function was achieved from β-γ alkynoic acids via hydrostannation, stannylcupration or silastannation reactions. Regioselectivity is highly dependent on the nature of the stannylanions used an...

摘要:Abstract(#br)The palladium catalysed coupling of organozinc or organotin reagents with 3-iodobut-2(or 3)-enoic acid is stereoselective and affords Z (or E )-3-methylalk-2-enoic acids. The method was applied to the synthesis of the E and Z stereoisomers of ocimenones and pseudo-ta...

摘要:Abstract(#br)Palladium catalysed regio- and stereoselective annulation of allenyl stannanes by β-iodo vinylic amides gives good yields of the corresponding 2-pyridones. This annulation probably occurs via a Stille reaction/cyclisation sequence.
