摘要： Amino acids are converted to their N-tertiary-butoxycarbonyl derivatives, which are especially useful for synthesis of polypeptides, by reacting a base addition salt of the amino acid with O-tertiary-butyl S-phenyl thiocarbonate.

摘要： A NEMATIC LIQUID CRYSTAL COMPOSITION HAVING A VERY BROAD MESOPHASE COMPRISING A MIXTURE OF AT LEAST TOW COMPOUNDS OF THE FORMULA:

(4-R-PHENYL)-CH=N-(1,4-PHENYLENE)-R1

WHEREIN EACH R AND R1 ARE RADICALS SELECTED FROM THE GROUP CONSISTING OF A SATRUATED ALKOXY RADICAL AND AN ALKYL RADICAL EACH HAVING FROM 1 TO 9 CARBON ATOMS AND ONLY ONE OF EACH R AND R1 IS ALKYL, AND AT LEAST ONE COMPOUND OF THE FORMULA:

(4-(R2-(COO)X-)PHENYL)-OOC-(1,4-PHENYLENE)-(OOC)Y-R3

WHEREIN R2 AND R3 ARESATURATED ALKOXY RADICALS OF FROM 1 TO 9 CARBON ATOMS, ONE OF X AND Y IS O AND THE OTHER IS 1.
