Approach to the hyacinthacines: first non-chiral pool synthesis of (+)-hyacinthacine A1.
نویسندگان
چکیده
The first non-chiral pool total synthesis of (+)-hyacinthacine A(1) is described. This synthesis is based on an effective [2 + 2] cycloaddition of dichloroketene to a Stericol-based enol ether, a diastereoselective dihydroxylation, and an efficient Tamao-Fleming oxidation.

The total synthesis of hyacinthacines B3, B4, and B5 and purported hyacinthacine B7, 7-epi-hyacinthacine B7, and 7a-epi-hyacinthacine B3 from a common anti-1,2-amino alcohol precursor is described. These syntheses confirmed that the proposed structures and absolute configurations of hyacinthacines B3, B4, and B5 were correct and disclosed that the proposed structure of hyacinthacine B7 was inco...

An efficient one-pot three-component procedure for the synthesis of new chiral spiro-oxindolopyrrolizidines with highly regio-, diastereo-, and enantioselective from 1,3-dipolar cycloaddition of azomethine ylides and optically pure active cinamoyl oxazolidinone are described. The process occurs at room temperature in aqueous ethanol as green solvent and in the absence of any bidentate chelating...
