The OPA-2amines-mediated end-to-side macrocyclization was efficient for peptide substrates of a wide range of ring sizes and AA compositions, affording the products in excellent regioselectivity in 10 min (Fig. 3b). Most of the reactions were completed within 2 min. Two examples that demon...
Two new glycosidic acids, quamoclinic acids G and H, were isolated from the glycosidic acid fraction afforded by alkaline hydrolysis of the ether-insoluble resin glycoside (convolvulin) fraction from the seeds of Quamoclit pennata BOJER. Both compounds are the first examples of bisdesmosides of ...

Both compounds were prepared from the corresponding heteroleptic tin(II) chloro-analogue, [Sn{2-[(Me3Si)2C]C5H4N}Cl], and thus demonstrate the utility of this compound as a precursor to further examples of heteroleptic tin(II) derivatives: such compounds are often unstable with respect to ...
