A new and rapid access to homochiral 2,3-dihydro-oxazolo[2,3-b]quinazolin-5-ones
摘要:
Starting from homochiral 1,3-oxazolidine-2-thiones 1, a two-step sequence led to homotopic 2,3-dihydro-oxazolo[2,3-b]quinazolin-5-one derivatives 3. The sequence was developed and studied regarding its scope and limitations. (C) 2001 Elsevier Science Ltd. All rights reserved.
Chemo-enzymatic preparation from renewable resources of enantiopure 1,3-oxazolidine-2-thiones
摘要:
Chiral 1,3-oxazolidine-2-thiones were prepared in enantiopure form from renewable resources through an enzymatic process involving immobilized myrosinase (thioglucoside glucohydrolase E.C. 3.2.3.1). (C) 2000 Elsevier Science Ltd. AII rights reserved.
