Heterocycles form, by far, the largest of the classical divisions of organic chemistry.
Moreover, they are of immense importance not only biologically and industrially but also to …

Catalytic asymmetric syntheses of enantioenriched propargyl alcohols and amines have
been a central topic in organic synthesis. Toward this, a great deal of research has been put …

Over the past decade, large strides have been achieved in the invention of methods for the
direct enantioselective addition of alkynes and metal alkynylide nucleophiles into prochiral …

A phosphine ligand served as a remarkable chemo-switch for the silver-catalyzed reaction of
alkynes with aldehydes in the presence of amines in water. Exclusive aldehyde− alkyne …

A C2-symmetric bisoxazolidine derived from aminoindanol has been successfully applied in
the asymmetric alkynylation of aldehydes. The ligand is readily available, has a wide …

The direct addition of organometallic reagents to carbonyl compounds is an efficient and
versatile method to generate CC bonds with concomitant formation of secondary and tertiary …

Asymmetric catalysis with chiral 1, 3-oxazolidine ligands, which have a sterically tunable,
rigid structure that can accommodate several chiral centers, has found increasing attention …

A facile and practical approach to preparation of enantiopure N-(ferrocenylmethyl) azetidin-2-
yl (diphenyl) methanol was developed from cheap and easily available l-(+)-methionine …

The first example of Cr-catalyzed asymmetric alkynylation of aldehydes with 1-iodo-and 1-
bromoalkynes was developed. The use of tethered bis (8-quinolinato) chromium catalyst (3 …

Herein, a highly efficient magnetically separable hybrid GO/SrFe12O19 nanocomposite was
synthesized via dispersing M-type strontium hexaferrite (SrFe12O19) on graphene oxide …
