Abstract

The synthesis of diphenyl[(R)-thiazolidine-4-carboxylato-O,N]boron 4, 9- borabicyclo[3.3.1]non-9-yl[(R)-thiazolidine-4-carboxylato-O,N]boron 9, 9- borabicyclo[3.3.1]non-9-yl[S-methyl-(R)-cysteinato-O,N]boron 10, and 9- borabicyclo[3.3.1]non-9-yl[S-trityl-(R)-cysteinato-O,N]boron 11 with potential application in Boron Neutron Capture Therapy is reported. The preparation of two derivatives of 2-oxo-propanoic acid, diphenyl[2- benzylimino-2-oxopropanoato-O,N]boron 6 and dicyclohexyl[2-imino-2- oxopropanoato-O,N]boron 8 is described. Compound 6 represents the first example of a monocyclic unsaturated oxazaborolidine-5-one whose crystal structure has been determined.
