Total Synthesis of Chiral Falcarindiol Analogues Using BINOL-Promoted Alkyne Addition to Aldehydes.
An enantioselective total synthesis of chiral falcarindiol analogues from buta-1,3-diyn-1-yltriisopropylsilane is reported. The key step in this synthesis is BINOL-promoted asymmetric diacetylene addition to aldehydes. The two chiral centers of the falcarindiol analogues can be produced by using the same kind of catalyst with high selectivity, and the final product can be obtained in only six s...
متن کاملStereoselective synthesis of N-heterocycles through amine addition to nitroalkenes.
An efficient route for the preparation of substituted N-heterocycles was developed through the amine addition to nitroalkenes. The reaction tolerates a large substrate scope with good to excellent yields (up to 95%) and excellent stereoselectivities (up to 99 : 1 dr).
متن کاملOne-pot synthesis of furocoumarins through cascade addition-cyclization-oxidation.
A novel one-pot cascade addition-cyclization-oxidation for the regioselective synthesis of furo[3,2-c]coumarins has been developed; the reaction is mild and easily handled without the necessity for dry solvents and inert atmosphere.
متن کاملAddition of diazoalkanes to alkyne(pentacarbonyl) /chromium and /tungsten */ formation of 3H-pyrazole complexes
Photolysis of [M(CO)6] (M /Cr, W) in CH2Cl2 at /78 8C generates [(CO)5M(CH2Cl2)]. Subsequent sequential reaction of [(CO)5M(CH2Cl2)] with terminal alkynes, HC /CR (R /COOMe, Ph, p -Tol), and diazoalkanes, R (R)CN2 (R 1 /Me, Et, Ph; R2 /Me, Et) affords 3H -pyrazole complexes, [(CO)5M / N N C(R) C(H) C /(R)(R)]. These complexes are derived from addition of diazoalkanes to alkyne complex intermedi...
متن کاملRapid Markovnikov addition of HCl to a pendant alkyne: evidence for a quinoidal cumulene.
Reaction of cis-[RuCl2(dppm)2]BF4 with TlBF4 and 1,4-diethynyl-benzenes results in the formation of the vinylidene cations trans-[Ru([double bond, length as m-dash]C[double bond, length as m-dash]CH-C6H2-2,5-R2-4-C[triple bond, length as m-dash]CH)Cl(dppm)2](+) (R = H, Me). Subsequent reaction with [N(n)Bu4]Cl results in nucleophilic attack at the coordinated organic ligand, but not at the expe...
