[13C2]-Coniferin was provided to a flax (Linum usitatissimum L.) cell suspension to monitor subsequent dimerisation by MS and NMR. The label was mainly incorporated into a 8-8′-linked lignan, lariciresinol diglucoside, a 8-5′-linked

The double labelled lignan precursors [1,2-13C 2]coniferin and the glucoside of [1,2-13C 2]ferulic acid were prepared by classical synthetic methods. Pure double labelled lignan precursors could only be obtained

Herein, we disclose the first set of unique selenium-containing SLAP (SiLicon Amine Protocol) reagents for the direct synthesis of C3/C5-substituted selenomorpholines and 1,4-selenazepanes fromdiverse (hetero)aldehydes under mild photocatalytic conditions. Enantiomerically pure 1,2-amino alcohol/α-amino acid versions of these heterocycles were also synthesized. Further, we have shown the late-stage modification of certain biologically active agents using the developed seleno-SLAPreagents.
Concise total synthesis of acylated phenolic glycosides vitexnegheteroin A and ovatoside D

Starting from readily available vanillin and α-D-acetobromo glucose, two natural acylated phenolic glycosides vitexnegheteroin A and ovatoside D were synthesized for the first time in 4 steps with overall yields of 54% and 65%, respectively. The key steps involve the directly regioselective O-6 acylation of vanillin β-D-glucopyranoside with acyl chlorides, and simultaneous removal of the allyl protecting groups on the phenolic acid moiety and reduction of the aldehyde in the aglycon moiety by using Pd(PPh)3-NaBH4 system in one pot.
