Group transfer potential Volume

Volume 1 includes nine chapters, the first six of these deal with the main established families of organic photochromes which have a few real and many potential applications. Their photochemical processes are based on pericyclic electrocyclic reactions. The three other chapters concern hydrogen or group rearrangement, and electron transfer. Seven out of the nine main authors, selected from all over the world, have not written chapters for previous books and importantly, three are from companies. Four chapters cover families not reviewed... 

The potential importance of the iridoid family of compounds was aheady mentioned previously in this volume (see Scheme 48 and 126). The Lupton group has reported recently the total synthesis of the natural product 7-deoxyloganin (625) 521). Synthesis of the bicyclic core was achieved by a NHC (626)-catalyzed rearrangement of the precursor 627 to furnish the lactone 628 in reasonable yield and with full transfer of stereo-information (Scheme 129), thus giving access to 625 after just three further steps.
