Palladium-Catalyzed Decarboxylative γ-Arylation for the Synthesis of Tetrasubstituted Chiral Allenes

An enantiospecific palladium-catalyzed decarboxylative coupling of acyclic β,γ-alkynoic acids with various aryl iodides to chiral tetrasubstituted allenes is described. The coupling reaction comprises a decarboxylative γ-palladation of α,α-disubstituted carboxylic acids to provide the tetrasubstituted allenes with complete point-to-axial chirality transfer in excellent yields.

Bifunctionalized allenes, Part IX: An efficient method for regioselective synthesis of 4-heteroatom-functionalized allenecarboxylates

An efficient method for regioselective synthesis of 4-heteroatom- functionalized allenecarboxylates by an atom economical [2,3]-sigmatropic rearrangement of the mediated 2-heteroatom-functionalized alk-3-ynecarboxylates is described. Alkyl 4-(dimethoxypho

Anticholinergic drugs

A class of anticholinergic drugs having the formula STR1 in which R1 is a carbocyclic or branched aliphatic group of 3 to 8 carbon atoms, R2 is a branched or linear aliphatic group containing 3 to 10 carbon atoms with 1 to 2 olefinic or acetylenic bonds and R3 is an alkyl or cyclic group of 4 to 12 carbon atoms containing a tertiary amino nitrogen, are described.
