CrCl2 Mediated addition of allylic halides or phosphates to N-protected α-amino aldehydes. Stereocontrolled synthesis of a new core for C2 symmetric HIV-protease inhibitors
摘要:
The addition of gamma-monosubstituted allylchromium(lll) reagents to N-protected alpha-amino aldehydes proceeds in a stereoconvergent manner in contrast with the case of the unsubstituted reagents, where the stereoselectivity depends on the nature of the group bonded to the nitrogen. The chromium(III) reagent derived from 3-chloromethyl-2-trimethylsilyl-1-propene was used to prepare a C-2 symmetric HIV-protease inhibitor. Copyright (C) 1996 Elsevier Science Ltd
