合成路线1
该中间体在本合成路线中的序号:(XXVII)3) The condensation of N-(tert-butoxycarbonyl)-L-phenylalaninal (XXV) with 2-(trimethylsilyl)thiazole (XXVI) by means of tetrabutylammonium fluoride gives the thiazole derivative (XXVII), which is cleaved by reaction with methyl iodide (formation of the thiazolium derivative) and treated with NaBH4 and HgCl2 to afford the protected 3(S)-amino-2(S)-hydroxy-4-phenylbutanal (XXVIII). Finally, this compound is reductocondensed with isoquinoline (XI) by means of sodium cyanoborohydride to yield the protected condensation product (XII), already obtained in scheme 16810301a.
