The preparation and enzymatic resolution of several cis-mono-4-O-protected-2-cyclopenten-1,4-diols are described. The process starts with inexpensive furfuryl alcohol and lends itself to the preparation of multigram quantities of various protected, optically active 2-cyclopenten-1,4-diol derivatives. Stereoselective reduction of 4-O-protected-2-cyclopentenone to the cis-mono-O-protected-2-cyclopenten-1
描述了几种顺式-单-4- O-保护的-2-环戊烯-1,4-二醇的制备和酶促拆分。该方法开始于廉价的糠醇,并有助于制备数克量的各种受保护的旋光性2-环戊烯-1,4-二醇衍生物。描述了使用或将4- O-保护的2-环戊烯酮立体选择性地还原为顺-单-O-保护的-2-环戊烯-1,4-二醇。随后对这些顺式-(+/-)-mono- O进行了胰酶促进的立体选择性酰化反应-经保护的环戊烯-1,4-二醇得到中等至极好的对映选择性的相应醇和乙酸酯。
