The comprehensive study of the reactions of carbonyl compounds and ethyl diazoacetate in the presence of a Br?nsted acid catalyst is described. In result, a broad range of 3-oxo-esters were synthesized from a variety of ketones and aliphatic aldehydes by 1,2-aryl/alkyl/hydride shift. Aryl-methyl ketones produced only aryl-migrated products, whereas other ketones yielded a mixture of products. For diaryl ketones, the identity of two inseparable migrated products was confirmed by two-dimensional NMR spectroscopy.

A novel dynamic kinetic resolution (DKR) of tetrasubstituted alkenyl cyanohydrins prepared from the corresponding α,β-unsaturated aldehydes is described. The deprotonation of a geometrical mixture of tetrasubstituted alkenyl cyanohydrins with sodium diiso
HIGH YIELD SYNTHESIS OF α PROPARGYLIC ACRYLIC ESTER : A GENERAL ACCESS TO α SUBSTITUTED ACRYLIC ESTERS

A heterogeneous mediated, high yield, monopropargylation of ethyl benzoylacetate followed by a methylenation reaction using a formaldehyde addition-benzoyl elimination mechanism is described.This useful method is extended to the synthesis of α substituted acrylic esters.
