Asymmetric synthesis of (-)-swainsonine
Lindsay, Karl B.,Pyne, Stephen G.
, p. 669 - 672 (2007/10/03)
This paper describes a new synthesis of (-)-swainsonine via the ring-closing metathesis reaction of a substituted 3-allyl-4-vinyloxazolindin-2- one and subsequent diastereoselective syn-dihydroxylation of the resulting pyrrolo[1,2-c]oxazol-3-one.
