  A practical synthesis of enantiopure 4,4,4-trifluoro-allo-threonine from an easily available fluorinated building block

  摘要：

  A practical method to prepare enantiopure 4,4,4-trifluoro-allo-threonine was developed by using an easily available fluorinated building block and a chiral auxiliary as starting materials. Trifluoroacetic anhydride was annulated with a ketene, derived from a glycine equivalent bearing a chiral oxazolidinone [(4S,5R)-4,5-diphenyloxazolidin-2-one], and acetone to afford a trifluoromethylated alpha,beta-unsaturated lactone. The asymmetric hydride reduction of the alpha,beta-unsaturated lactone proceeded with excellent stereoselectivity to give the corresponding (2R,3S)-4-oxapentan-5-olide derivative exclusively (diastereopurity, 99%). From the reduced product thus obtained, protecting groups were readily removed by acid treatment and subsequent catalytic hydrogenolysis to afford enantiopure (2R,35)-4,4,4-trifluoro-allo-threonine in an excellent yield (7 steps, 51% overall yield).

  AbstractN‐[Bis(trimethylsilyl)methyl]imines 9 show unique chemical properties when compared with conventional imines. Their reaction with optically pure aminoketenes derived from dehydrochlorination of 14 and 15 affords the corresponding 3‐amino‐4‐alkyl‐β‐lactams 16 and 17 in good yields and high diastereoselectivities. The mild deprotection of bis(trimethylsilyl)methyl‐ and phenyloxazolidinone moieties with, respectively, cerium(IV) ammonium nitrate and lithium/ammonia or hydrogen/Pd(OH)2 allows the preparation of a variety of β‐lactam antibiotic building blocks.
