Synthesis of (±)-homogabaculine and (±)-homoshikimic acid
摘要:
Syntheses of homogabaculine and homoshikimic acid are described utilising the base mediated ring opening of the cycloadducts of methyl acrylate and N-carbamoyl-1,2-dihydropyridines.
A novel chiral oxazolidine organocatalyst for the synthesis of an oseltamivir intermediate using a highly enantioselective Diels–Alder reaction of 1,2-dihydropyridine
Enantioselective DielsâAlder reactions of 1,2-dihydropyridines with acroleins using a novel chiral oxazolidine organocatalyst afforded chiral isoquinuclidines that is an efficient synthetic intermediate of oseltamivir, with fairly good chemical yield and excellent enantioselectivity (90%, up to >99% ee).

developed a novel approach for the synthesis of enantioenriched 3-boryl-tetrahydropyridines via the Cu(I)-catalyzed regio-, diastereo-, and enantioselective protoborylation of 1,2-dihydropyridines, which were obtained by the partial reduction of the pyridine derivatives. This dearomatization/enantioselective borylation stepwise strategy provides facile access to chiral piperidines together with the stereospecific

The synthesis of (±)-3-(1-carboxy-3α,4α-dihydroxycyclohex-1-en-5β-yl)-2-methylidenepropionic acid, a methylene analogue of 5-enolpyruvylshikimic acid, from methyl 3α,4α-isopropylidene-5β-iodomethylcyclohex-1-ene-1-carboxylate is described. The starting compound is obtained from (±)-methyl homogabaculate. In addition, both enantiomers of methyl homogabacuate have been synthesised from a Diels-Alder
