Abstract/OtherAbstract:
A convenient and simple synthetic method of dodecaboratethio-l-amino acid, a new class of tumor-seeking boron carrier for BNCT, was accomplished from S-cyanoethylthioundecahydro-closo-dodecaborate (S-cyanoethyl-(10)BSH, [(10)B(12)H(11)](2-)SCH(2)CH(2)CN) and bromo-l-α-amino acids by nearly one step S-alkylation. An improved synthesis of S-cyanoethyl-(10)BSH, a key starting compound for S-alkylation, was also performed by Michael addition of (10)BSH with acryronitrile in high yield. Four kinds of new dodecaboratethio-l-amino acids were obtained in optically pure form without the need for any optical resolution.
