3]-sigmatropic rearrangement has been used to access biologically important β,β′-dihydroxy α-amino acids. The rearrangement reported is highly stereoselective and offers excellent levels of remotestereocontrol. This strategy has been used to synthesize the natural immunosuppressant mycestericin G and ent-mycestericin G, allowing for a revision of absolute configuration of this natural product.

The Ireland−Claisenrearrangement of 3-alkoxy- and 3-aryloxy-substituted allyl glycinates is presented. This [3,3]-sigmatropic rearrangement route offers direct access to syn β-alkoxy and β-aryloxy α-amino acid systems. In particular, N,N-diboc glycine esters rearrange with excellent diastereoselectivities (dr > 25:1). The synthesis of substrates, rearrangement optimization, and a discussion of stereoselection
A compound represented by the following general formula (1), or a salt thereof has serine protease inhibiting activity, and particularly excellent inhibiting activity against clotting factor VIIa. This compound or a salt thereof is useful as therapeutic and/or prophylactic agents for diseases associated with thrombus formation.
