      A short, facile and efficient synthesis of D-lyxo-phytosphingosine analogue has been achieved. The key steps involved are the Baylis-Hillman reaction of (S)-Garner aldehyde with methyl acrylate to obtain the corresponding adduct as the potential substrate, to which was added decylmagnesium bromide to obtain the E-trisubstituted alkene followed by OsO4/NMO mediated dihydroxylation gave the desired D-lyxophytosphingosine analogue intermediate diol which on acid hydrolysis resulted in the formation of the target molecule in good yield.

      The field of coordination polymers (CPs) has grown rapidly in the recent time and exemplifies one of the most exciting fields in the solid state and structural chemistry. In order to search for new CPs with desirable structural features and attractive functional properties, various synthetic strategies have been adopted including the challenging metalloligand approach. This approach relies on developing a metalloligand that is capable of placing the appended functional groups to limited directions thus resulting in limited structural variations—alandmark step towards predictable architectures. Consequently, a variety of metalloligands offering assorted functional groups have been developed and explored for the construction of noteworthy CPs. This perspective article summarizes an important class of metalloligands offering appended carboxylic acid groups with a focus on the design strategies to understand the architectures of the resultant CPs being controlled by the metalloligands. In addition, a concise discussion has been included about the applications of selected CPs to demonstrate their practical utilization.
