Exploring the synthesis of conduritol derivatives: strategies, challenges, and advances

Abstract

Conduritol derivatives represent an important class of cyclitol-based molecules characterized by structural diversity, synthetic flexibility, and notable biological activity. Built on a cyclohexene core bearing multiple hydroxyl groups, conduritols have attracted sustained interest due to their potent glycosidase inhibitory properties and their occurrence in biologically active natural products such as pancratistatin and lycoricidine. The parent compound exists as six diastereomeric forms, and extensive methodological advances over recent decades have enabled access to all stereoisomers as well as a wide range of functionalized derivatives, including epoxidized, aminated, halogenated, and selectively protected analogues. Many of these compounds have shown promise as enzyme inhibitors and as leads for anticancer, antileukemic, and antimicrobial applications. Building on earlier work focused on the synthesis of conduritol stereoisomers, this review concentrates on strategies for the preparation of conduritol derivatives, emphasizing asymmetric synthesis, stereoselective functionalization, and recent developments in catalytic and green chemistry approaches. Key challenges related to regio- and stereocontrol are critically discussed, along with comparative assessments of established and emerging synthetic routes. The therapeutic relevance of conduritol derivatives, particularly in glycosidase-targeted interventions for metabolic and proliferative diseases, is also highlighted, providing an integrated perspective on current advances and future opportunities in this field. By consolidating and critically evaluating the diverse synthetic methodologies developed to date, this review aims to serve as a comprehensive resource for the research community, highlighting existing methodological gaps and guiding the design of more efficient, selective, and sustainable strategies for the synthesis and application of conduritol-based frameworks.
