Strand, Daniel,Norrby, Per-Ola,Rein, Tobias
, p. 1879 - 1891 (2007/10/03)
Syntheses of the nonclassical annonaceous acetogenins, pyranicin, and pyragonicin from common late-stage intermediates are presented. The construction of key elements relies on asymmetric HWE reactions, including the desymmetrization of a meso-dialdehyde
Total synthesis of pyranicin
Strand, Daniel,Rein, Tobias
, p. 199 - 202 (2007/10/03)
(Chemical Equation Presented) A stereocontrolled convergent synthesis of the annonaceous acetogenin pyranicin (1) is presented. Asymmetric Horner-Wadsworth-Emmons (HWE) reactions were used to access key intermediates. The tetrahydropyran derivative 2 was

(Formula presented) A racemic aldehyde can undergo parallel kinetic resolution (PKR) by simultaneous reaction with two different chiral phosphonates, differing either in the structure of the chiral auxiliary or in the structure of the phosphoryl group (i.
