One-Pot Synthesis of 1-(1-Alkoxyethoxy)allenes
Tarasova,Nedolya,Albanov
, p. 1831 - 1834 (2019/03/26)
A convenient one-pot procedure has been proposed for the preparation of 1-(1-alkoxyethoxy)allenes from alkoxyethenes and prop-2-yn-1-ol with the use of trifluoroacetic acid as highly efficient catalyst for the synthesis of 3-(1-alkoxyethoxy)prop-1-ynes and of the system t-BuOK–DMSO for the isomerization of the latter into allenes.
Synthesis of 3-hydroxy-1-methyl-2-(methylthio)pyrrole from methyl isothiocyanate and prop-2-yn-1-ol
Brandsma,Nedolya,Trofimov
, p. 1634 - 1636 (2007/10/03)
A methylated adduct of lithiated 1-(1-ethoxyethoxy)allene and methyl isothiocyanate undergoes intramolecular cyclization in the presence of CuBr to give 3-(1-ethoxyethoxy)-1-methyl-2-(methylthio)pyrrole. The methanolysis of the latter affords 3-hydroxy-1-methyl-2-(methylthio)pyrrole.
ALLENE ETHERS FOR THE CATIONIC CYCLOPENTANNELATION
Tius, Marcus A.,Ousset, J-B.,Astrab, Donald P.,Fauq, Abdul H.,Trehan, Sanjay
, p. 923 - 924 (2007/10/02)
Only allene ethers having a group which is capable of departing as a stable cation participate successfully in the cationic cyclopentannelation reaction.
SILYL KETONE CHEMISTRY. PREPARATION AND REACTIONS OF UNSATURATED SILYL KETONES
Reich, Hans J.,Kelly, Martha J.,Olson, Richard E.,Holtan, Ronald C.
, p. 949 - 960 (2007/10/02)
A series of silyl ketones has been prepared by appropriate manipulation of α-silylated allenol ethers.Among the compounds prepared were alkenyl, alkynyl and acyl silyl ketones.The spectroscopic properties of representative members of these classes of comp
