Asymmetric access to α-hydroxy-1,4-diketones has been achieved by direct ene coupling of silyl enol ethers with glyoxal electrophiles, mediated by a chiral N,N′-dioxide–nickel(II) complex catalyst. Successful union of a polyketide silyl enol eth

2-Bromo-1,3-butadienes are demonstrated to be effective substrates for tandem Diels-Alder/transition metal cross-coupling reaction sequences. Intermolecular cycloaddition of a 2-bromo-1,3-diene with activated dienophiles proceeded under Lewis acid ca

Aminoacylated transfer RNAs, which harbor a covalent linkage between amino acids and RNA, are a universally conserved feature of life. Because they are essential substrates for ribosomal translation, aminoacylated oligonucleotides must have been pres

Stereoselective synthesis of the C4-C16 polyketide fragment of portimines A and B is reported, enabled by our previously established method for the stereoselective synthesis of syn-α,α'-dihydroxyketones. The preparation of this advanced fragment pr

The first synthesis of leptosin, a novel glycoside isolated from mānuka honey is described. Utilising an acetyl protecting group strategy the glycoside was obtained with excellent anomeric selectivity by deploying a Schmidt glycosylation as a key st

Many studies have demonstrated that allograft tolerance can be achieved in inbred rats and mice following intrathymic injection of donor cells or antigen and treatment with antilymphocyte serum (ALS). In outbred dogs, xenografts, and inbred rat strai

This article describes our efforts to develop an asymmetric synthesis of bisbenzannulated spiroketals using a chiral sulfoxide auxiliary. Our primary focus was on the synthesis of the 3H-spiro[benzofuran-2,2'-chroman] ring system, the spirocyclic cor
