摘要：

The title compound (S, S)-2, has been obtained by reduction with Li[AlH4] of the cyclopentane-1,2-diyl-bis(1',3',2'-dioxaphospholane (1 S,2S)-trans-C5H8[P(OCH(CO2Pr-i)-(R)-)(2)](2), (S,S)-1, which itself was isolated in diastereomerically pure form (X-ray structure analysis) from the reaction between me, trans-C5H8(PCl2)(2) and (2R,3R)-(+)-disopropyl tartrate. Cleavage of (S,S)-1 with PCl3 yielded an unseparable mixture of (1S,2S)-trans-C5H8(PCl2)(2) and (4R,5R)-CIP[OCH(CO2Pr-i)-](2).
