demonstrated. The reaction is both chemoselective and syn-selective, making it complementary to the anti-selective cross-benzoin reaction of NHBoc-α-amino aldehydes. Good diastereoselectivity is obtained for a variety of amino aldehydes, including nonhindered ones. A Felkin–Anh model can be used to rationalize the observed diastereoselectivity.
证明了在与杂芳族醛的交叉安息香反应中利用N -Bn - N - Boc -α-氨基醛的有效性。该反应是化学选择性两者和顺式-选择性,使其互补于抗-选择性交叉安息香反应Ñ HBOC-α氨基醛。对于多种氨基醛,包括非受阻醛,都具有良好的非对映选择性。Felkin-Anh模型可用于合理化所观察到的非对映选择性。

The treatment of a 1,2,5-thiadiazolidine 1,1-dioxide-derived phenylthiomethyl ether with sulfuryl chloride yielded an unexpected dimeric product whose structure was determined using X-ray crystallography. A plausible mechanism for the formation of this product is proposed. J. Heterocyclic Chem. (2009).

A general synthesis of 4-keto-4,5,6,7-tetrahydroindoles 6–12 has been achieved in two steps using a new intramolecular1,3-dipolarcycloadditionapproach in moderate yields (45–60%). The potential of this methodology is demonstrated by the synthesis of a mitomycin skeleton (15) and a topoisomerase-1 inhibitor skeleton (17).
