Relevant academic research and scientific papers

A de novo asymmetric approach to achiral deoxy-melodorinol analogues

A short and highly efficient route to deoxy-Melodorinol analogues has been developed. The key to the overall transformation is the use of an enantioselective Sharpless asymmetric dihydroxylation of an (Z,E)-dienoate to control the regioselectivity of the dihydroxylation reaction and a Mitsunobu elimination reaction to control the E-stereochemistry of the,δ-double bond. The highly efficient synthesis stereoselectively prepared four analogues in 3 steps from 4-substituted crotonaldehydes.

De novo asymmetric syntheses of D- and L-talose via an iterative dihydroxylation of dienoates

A short and highly efficient route to D- and L-tafo-γ-lactones has been developed. The key transformation was the sequential osmium-catalyzed bis-dihydroxylation reaction of substituted 2,4-dienoates. When the first dihydroxylation reaction is performed o

Palladium-catalyzed stereospecific epoxide-opening reaction of γ,δ-epoxy-α,β-unsaturated esters with an alkylboronic acid leading to γ,δ-vicinal diols with double inversion of the configuration

A palladium-catalyzed stereospecific epoxide-opening reaction of γ,δ-epoxy-α,β-unsaturated esters with an alkylboronic acid leading to γ,δ-vicinal diols is described, which proceeds with retention of the configuration, i.e., via two consecutive SN/s

Addition of Organocopper Reagents to Cyclic Sulfites or Carbonates of γ,δ-Dihydroxy (E)-α,β-Enoates

Reaction of cyclic sulfites or carbonates of γ,δ-dihydroxy (E)-α,β-enoates with R2Cu(CN)Li2, BF3; RCu(CN)Li, BF3 (R=Me-, n-Bu-) afforded either diastereoselective SN2' products or reductive elimination product depending on reaction conditions.Addition of R2Cu(CN)Li2, BF3 (R=Me-, n-Bu-) to cyclic sulfite (1) or cyclic carbonate (3) (inverse addition) afforded highly regio-, (E)-stereo- and diastereoselectivity α-alkylation products (6 and 8).By using this methodology, (2S, 5S)-trans-2-methyl-5-hexanolide, the pheromone of the carpenter bee Xylocopa hirutissima was synthesized.
