New N-Boc-alkyl(2-alkynylcyclopropyl)amines were synthesized from 1-alkynyl-1-chlorocyclopropanes and N-Boc- alkylamines under the action of ButOK in DMSO, the intermediates having been the corresponding conjugated alkynylcyclopropenes. The Boc-deriv

3,3-Disubstituted piperidin-2-ones were obtained by alkylation of carboxylic acid esters with 1-(3-halopropyl)-2,5-dimethylpyrroles using lithium diisopropylamide as a base followed by the removal of 2,5-dimethylpyrrole protection and intramolecular

1-Alkynyl-1-chlorocyclopropanes undergo chlorine-lithium exchange on treatment with BunLi in THF at -40—0 °C. Thus generated organolithium species react with carbon dioxide (dry ice) and acetone to give selectively hitherto unknown 1-alkynylcyclop

New singlet alkylthio(4-methylpent-3-en-1-ynyl)carbenes were generated by photolysis of corresponding 5-alkylthioethynyl-3,3-dimethyl-3H-pyrazoles and subsequently trapped by alkenes giving rise to 1-alkynyl-1-(alkylthio)cyclopropanes in yields up to

One-pot cyclization of alk-4-ynals with primary aliphatic amines and azoles in DMSO under the action of KOH affords 1-alkyl-2-azolyl-5-arylmethylidenepyrrolidines. Similar processes with lithium monoalkylamides in THF give rise to 3-iminocyclopentene
