Abstract

The isolation from $Alexa leiopetala$ and identification by X-ray crystal structure analysis of (1R,2R,3R,7S,8S)-3-hydroxymethyl-1,2,7-trihydroxypyrrolizidine [(2R,3R,4R,5S,6S)-2-hydroxymethyl-1-azabicyclo[3.3.0]octan-3,4,6-triol], a unique pyrrolizidine alkaloid, is described. A preliminary study of the inhibition of glycosidases by alexine is reported.

The isolation from $Alexa leiopetala$ and X-ray crystal structure of alexine (1) is reported.

Enantiospecific Total Synthesis of (−)-Hyacinthacine A<inf>1</inf> and (+)-Hyacinthacine A<inf>1</inf> and Their Homologues Using Nitrogen Substituted Donor–Acceptor Cyclopropane
2023, European Journal of Organic Chemistry
A concise and efficient enantiospecific total synthesis of (−)‐hyacinthacine A₁ and (+)‐hyacinthacine A₁ was achieved from commercially available starting material L‐pyroglutamic acid and D‐glutamic acid, respectively. For the synthesis of this trihydroxylated pyrrolizidine ring, we employed the nitrogen‐substituted donor‐acceptor cyclopropane as a key intermediate. The synthetic approach relies on two crucial steps, highly stereo‐ and regioselective intramolecular cyclopropanation with Rh₂(OAc)₄ and regioselective ring opening of a nitrogen‐substituted donor‐acceptor cyclopropane.
Pyrrolizidine Alkaloids
2018, Alkaloids: Chemistry and Biology
Naturally occurring pyrrolizidine alkaloids (PAs) are isolated from plants and other sources. The interest of the scientific community in these compounds owes itself to their high toxicity and biological activity, as well as to the challenge of synthesizing their pyrrolizidine scaffold. This review encompasses a wide range of topics found in the literature from 1995 to date, including the occurrence, biosynthesis, toxicity (hepatotoxicity, genotoxicity, and tumorigenicity), biological activity, and pharmacological properties (glycosidase inhibitory activity) of these secondary metabolites. Particular attention is given to the chemistry of PAs, addressing general strategies for formal and total syntheses via amino-based substrates, pyrroles, and pyrrolidine-based derivatives.
Isolation and SAR studies of bicyclic iminosugars from Castanospermum australe as glycosidase inhibitors
2015, Phytochemistry
We report the isolation and structural determination of fourteen iminosugars, containing five pyrrolizidines and five indolizidines, from Castanospermum australe. The structure of a new alkaloid was elucidated by spectroscopic methods as 6,8-diepi-castanospermine (13). Our side-by-side comparison between bicyclic and corresponding monocyclic iminosugars revealed that inhibition potency and spectrum against each enzyme are clearly changed by their core structures. Castanospermine (10) and 1-deoxynojirimycin (DNJ) have a common d-gluco configuration, and they showed the expected similar inhibition potency and spectrum. In sharp contrast, 6-epi-castanospermine (12) and 1-deoxymannojirimycin (manno-DNJ) both have the d-manno configuration but the α-mannosidase inhibition of 6-epi-castanospermine (12) was much better than that of manno-DNJ. 6,8-Diepi-castanospermine (13) could be regarded as a bicyclic derivative of talo-DNJ, but it showed a complete loss of α-galactosidase A inhibition. This behavior against α-galactosidase A is similar to that observed for 1-epi-australine (6) and altro-DMDP.
