  Chirality Transfer from Guanidinium Ylides to 3-Alkenyl (or 3-Alkynyl) Aziridine-2-carboxylates and Application to the Syntheses of (2R,3S)-3-Hydroxyleucinate and d-erythro-Sphingosine

  摘要：

  Reaction of chiral guanidinium ylides with alpha,beta-unsaturated aldehydes gives 3-(alpha,beta-unsaturated) aziridine-2-carboxylates in high diastereo- and enantioselectivities (up to 93% diastereomeric excess and 98% enantiomeric excess). 3-(l-Methylvinyl)- and 3-[(E)-pentadec-1-enyllaziridine-2-carboxylates were successfully employed to prepare (2R,3S)-3-hydroxyleucinate and D-erythro-sphingosine, respectively.
