Halolactonization is an electrophilic anti-addition to a C=C double bond; therefore, it is a highly stereoselective reaction
. The halolactones 3-8 being formed in the process have, at all times, the trans-orientation of the substituents introduced and, for a fixed configuration of the C=C double bond, halolactones are formed in a diastereoselective manner.
We want to exploit their potential of non-covalent interactions in chemo-, regio- and stereoselective reactions
by using triptycene scaffolds for the synthesis of iodine-based reagents.

GC technology enabled us the microanalysis of sterol mixtures and the synthetic organic chemistry made it possible to prepare all stereoisomers through the stereoselective reactions
at the steroid side chains.
Polymeric enzymes analogues are used in many reactions such as hydrolysis reactions, Diels-Alder aldol condensation, isomerization, and stereoselective reactions
, and regioselective reactions [3, 5, 8,18-20].
This 43rd volume in the annual series responds to the considerable interest in applying stereoselective reactions
by flagging reactions that occur with significant diasterometric or enantiometric excess with de or ee in the margin.
Siva's program involves synthetic effort that allows a freedom of design to produce new structural motifs not only for studying stereoselective reactions
, but also for chemical and bio-molecular recognition of encapsulated guests within water soluble nano-reaction vessels.
The goal of the book is to aid professors, researchers, and students in proposing reasonable transition states for the description of newly discovered stereoselective reactions
