of appropriate internal standards for quantification. Herein we describe the synthesis of a variety of 1-deoxy-sphingoid bases. 1-DeoxySphingolipids have recently acquired significant attention due to its pathological role in the rare inherited neuropathy, HSAN1 but also as predictive biomarkers in diabetes type II. Some of the compounds synthesized and characterized herein, have been used and will

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
Diastereoselective C-3-clongation processes of N-Boc-, N-Z-, N-Bn-N-Boc-, and N-Bn-N-Z-L-alaninals (Boc = BuOCO, Z PhCH2OCO, Bn = PhCH2) using various allyl reagents, such as allyl bromide in the presence of Zn/aqueous NH4Cl solution. of SnCl2 . 2 H2O/NaI or of Mg/CuCl2 . 2 H2O, as well as allyltrichlorosilane. are described. A substantially different influence of the N-protecting groups replacing either one or two amino protons was observed, allowing the selective synthesis of either the syn- or anti-diastereoisomer as a major product.
