39657-45-9, Name is Isoxazolidine hydrochloride, belongs to oxazolidine compound, is a common compound. category: oxazolidineIn an article, once mentioned the new application about 39657-45-9.
A three-step synthesis of N-(9-(9-phenylfluorenyl)-L-alaninal (5) from alanine is described.Exposure to silica or nonnucleophilic base causes no detectable racemization of this alpha-amino aldehyde.The 9-(9-phenylfluorenyl) N-protecting group also maintains the configurational integrity of alpha-amino aldehyde 5 during C-C bond-forming reactions, providing enantiomerically pure products from Wittig reaction, aldol condensation, and addition of Grignard reagent.
