Paragraph 0069; 0070, (2014/11/13)
As shown by the following formula (1), after methyl laurate (2 mmol) and water (8 mL) are added to an ammonium pyrosulfate catalyst (5 mol%), a hydrolysis reaction of methyl laurate is carried out by heating for 24 hours at 60°C while stirring is performed, so that lauric acid can be obtained with a yield of 86%.

The stereocontrolled synthesis of seven 2-substituted-4-carboxy-3,4,5,6- tetrahydropyrimidines bearing either one chiral center at C-4 or two chiral centers at C-4 and C-8 was performed by condensation of (S)- or (R)- 2,4- diaminobutyric acid (Daba) with iminoethers derived from glycine, (S)- and (R)- serine, (S)- and (R)- tyrosine. Under the conditions reported, epimerization was always completely prevented at the C-4 center, whereas at the C-8 center, it was completely avoided in the case of tyrosine derivatives and considerably diminished for the serine derivatives.

(2S,3R) Threo-3-hydroxy-ornithine has been synthesized efficiently using a highly stereoselective iodocyclocarbamation of the chiral Z-olefin 7 prepared from D-serine.
