, p. 369 - 374 (2013/04/23)
Dihydrocodeine and hydrocodone were synthesized from bromobenzene in 16 and 17 transformations, respectively. The key steps involved the toluene dioxygenase-mediated dihydroxylation of bromobenzene by whole-cell fermentation with E. coli JM109(pDTG601A), Kazmaier-Claisen rearrangement of glycinate ester, Claisen rearrangement to set the C-13 quaternary center, and C-10-C-11 closure. Experimental procedures are provided for the key steps. Georg Thieme Verlag Stuttgart . New York.
Chemoenzymatic synthesis of functionalized cyclohexylglycines and α-methylcyclohexylglycines via Kazmaier-Claisen rearrangement

The synthesis of homochiral functionalized cyclohexylglycines and α-methylcyclohexylglycines via chelated Kazmaier-Claisen rearrangement is described. These were shown to be potent scaffolds for the development of MMP inhibitors.
