Abstract
The absolute configuration of the title cis-(1R,3R,4S)-pyrrolidine-borane complex, C(18)H(34)BNO(2)Si, was confirmed. Together with the related trans isomers (3S,4S) and (3R,4R), it was obtained unexpectedly from the BH(3) x SMe(2) reduction of the corresponding chiral (3R,4R)-lactam precursor. The phenyl ring is disordered over two conformations in the ratio 0.65:0.35. The crystallographic packing is dominated by the rarely found donor-acceptor hydroxy-borane O-H...H-B hydrogen bonds.
