Stereoselective synthesis of (-)-acanthoic acid.
[reaction: see text] The first stereoselective synthesis of (-)-acanthoic acid (1) has been designed and accomplished. Our synthetic plan departs from (-) Wieland-Miesher ketone (7) and calls upon a Diels-Alder cycloaddition reaction for the construction of the C ring of 1. The described synthesis confirms the proposed stereochemistry of 1 and represents an efficient entry into an unexplored cl...
متن کاملMonocarboxylic acid transport.
Monocarboxylates such as lactate, pyruvate, and the ketone bodies play major roles in metabolism and must be transported across both the plasma membrane and mitochondrial inner membrane. A family of five proton-linked MonoCarboxylate Transporters (MCTs) is involved in the former and the mitochondrial pyruvate carrier (MPC) mediates the latter. In the intestine and kidney, two Sodium-coupled Mon...
متن کامل[Stereoselective synthesis of polyhydroxylated amines using (S)-pyroglutamic acid derivatives].
Naturally occurring polyhydroxylated amines such as (+)-1-deoxynojirimycin, polyoxamic acid, anisomycin, (-)swainsonine, and alexine stereoisomers, which have interesting biological activities including glucosidase- and mannosidase-inhibitory activity, immunoregulatory activity, and antibacterial effects, were synthesized stereoselectively starting from (S)-pyroglutamic acid derivatives. α,β-Un...
متن کاملStereoselective synthesis of (-)-spicigerolide.
(-)-Spicigerolide was stereoselectively synthesized from a protected (S)-lactaldehyde. The synthesis of the polyacetylated framework relied on two Zn-mediated stereoselective additions of alkynes to aldehydes as well as a regiocontrolled [3,3]-sigmatropic rearrangement of an allylic acetate. The pyranone moiety was constructed via ring-closing metathesis.
متن کاملStereoselective synthesis of (+)-polyoxamic acid based on the synthesis of chiral oxazine.
A concise, stereocontrolled synthesis of (+)-polyoxamic acid was achieved. Starting from trans-oxazoline as a chiral building block, the key step involves diastereoselective oxazine formation catalyzed by palladium(0).
