Negishi, Shoko; Ishibashi, Hiroyuki; Matsuo, Jun-ichi published the artcile< Asymmetric Synthesis of 2,3-Dihydro-4-pyranones by Reaction of Chiral 3-Alkoxycyclobutanone and Aldehydes>, COA of Formula: C6H10O5, the main research area is asym dihydropyranone preparation diastereoselective cycloaddition; diastereoselective cycloaddition chiral alkoxycyclobutanone aldehyde reactant dihydropyranone preparation; titanium tin chloride mediated diastereoselective cycloaddition enantioselective dihydropyranone preparation.
Chiral cyclobutanone I, which has Et L-lactate as a chiral auxiliary at the 3-position, reacted with aldehydes to give 2,3-dihydro-4-pyranones, e.g. II, in up to 93% ee by combined use of titanium(IV) chloride and tin(II) chloride.
Organic Letters published new progress about Aryl aldehydes Role: RCT (Reactant), RACT (Reactant or Reagent). 617-55-0 belongs to class esters-buliding-blocks, and the molecular formula is C6H10O5, COA of Formula: C6H10O5.
