  摘要：

  在含2％水的THF中用NaBH 4还原各种N-叔丁烷亚磺酰基亚胺，从而以高收率和非对映选择性提供相应的仲亚磺酰胺。通过使用相同的亚磺酰基亚胺原料并将还原剂更改为L-Selectride，可以有效地逆转立体选择性，从而以高收率和选择性提供相反的产物非对映异构体。

  The first diastereoselective allylation reaction at the α-position of ketones by using tert-butanesulfinamide as a chiral auxiliary is explored. Excellent yields and high diastereomeric ratios were achieved under palladium catalysis in the presence of a readily available achiral phosphine ligand. The chiral auxiliary was removed in quantitative yield under the optimized conditions without any racemization

• Synthesis of Enantiomerically Pure <i>N</i>-<i>tert</i>-Butanesulfinyl Imines (<i>tert</i>-Butanesulfinimines) by the Direct Condensation of <i>tert</i>-Butanesulfinamide with Aldehydes and Ketones

  Experimental details for the first general methods for the one-step preparation of N-tert-butanesulfinyl imines (tert-butanesulfinimines) (2) from aldehydes and ketones is described. To effect the condensations of tert-butanesulfinamide (1) with aldehydes, the Lewis acidic dehydrating agents MgSO4, CuSO4, or Ti(OEt)(4) are employed. Aldehyde condensations mediated by MgSO4 proceed in high yields (84-96%) when an excess of aldehyde is used. In contrast, only a slight excess of aldehyde (1.1 equiv) relative to tert-butanesulfinamide provides sulfinimines in high yields when the more Lewis acidic dehydrating agent CuSO4 is used. The CuSO4-mediated procedure is effective for a wide range of aldehydes, including sterically demanding aldehydes, such as isobutyraldehyde (90%), and electron-rich aldehydes, such as p-anisaldehyde (81%). The still more Lewis acidic Ti(OEt)(4) and Ti(O-i-Pr)(4) also afford N-tert-butanesulfinyl aldimines from especially unreactive aldehydes, such as pivaldehyde (82%). In addition, Ti(OEt)(4) is effective for the condensation of I with ketones to afford a wide range of N-tert-butanesulfinyl ketimines in good yields (77-91%). For sulfinyl ketimines derived from methyl or n-alkyl phenyl ketones and methyl or n-alkyl isopropyl ketones, only the E isomer is detected by H-1 and C-13 NMR in CDCl3. For those cases where the difference in steric demand about the imine is very small, such as for 2-hexanone, high E/Z ratios are still observed (5:1).

  [GRAPHIC]A one-pot method for the asymmetric synthesis of tert-butanesulfinyl-protected amines is described. Condensation of aryl alkyl and dialkyl ketones with tert-butanesulfinamide followed by in situ reduction with the appropriate reagent provides either diastereomer of the sulfinamide products in good yields and with diastereomeric ratios of up to 99:1.

  general method is described for asymmetric synthesis of both syn- and anti-1,3-amino alcohols. The first application of metalloenamines derived from N-sulfinyl imines is reported for the highly diastereoselective addition to aldehydes. The reduction of the product beta-hydroxy N-sulfinyl imines 2 with catecholborane and LiBHEt(3) provides syn- and anti-1,3-amino alcohols with very high diastereomeric
