Abstract
The X-H insertion reaction constitutes a powerful tool to create diversity through the diazo decomposition of diazocarbonyl compounds. However, until now, X-H insertion on α-diazo-β-aryl-β-hydroxyester scaffolds, readily prepared by aldol-type addition, remained a challenge for the organic chemist. We report herein the first O-H insertions on O-protected α-diazo-β-aryl-β-hydroxyesters, providing straightforward access to a wide range of α,β-dioxygenated esters through modulation of the alcohol and of the aryl substituent. The key feature to achieving this transformation is the use of Rh(I) catalysts, which proved to be crucial to favor the targeted O-H insertion product over the competing 1,2-H and 1,2-Ar migration products. Overall, 32 O-H insertion products have been prepared, in moderate to good yields, with a diastereoisomeric ratio up to 7.5:1 in favor of the syn diastereoisomer.

Abstract
A Lewis acid mediated conjugate addition of isocyanides to β-hydroxy-α-diazo carbonyls has been developed for the first time. The reaction realizes the efficient construction of quaternary carbon centers and provides a novel and efficient strategy for the synthesis of β-carboxamido-α-diazo carbonyls that would be otherwise difficult to form in a single step. Further applications, including synthesis of methylenecyclohexane, spiro-β-lactam, and nitrogen-bridged tricyclic β-lactam, demonstrated the tremendous potential of the coupling reaction.

Abstract
Acid-catalyzed decomposition of diazocarbonyl compounds triggers a wide range of transformations leading to synthetically useful building blocks with high diversity. In this field, the chemistry of α-diazo-β-hydroxy ester substrates is largely dominated by migration processes. We describe herein a new approach to original mixed monosilyl acetals from O-protected α-diazo-β-hydroxy-β-aryl esters and alcohols, catalyzed by trimethylsilyl trifluoromethanesulfonate (TMSOTf). The ratio between these original mixed acetals, the symmetric acetals, and the migration products fluctuates depending on the catalyst, the nature of the alcohols, and the substituent on the aromatic ring. Fifty-six examples are reported herein with yields up to 71% and diastereoselectivity up to 6:1. Such mixed monosilyl acetals constitute a synthetic equivalent of α-substituted β-oxoesters with high potential for further transformations.

Abstract
A proposed structure for schizocommunin (Z)-1(hydroxy) and its geometric isomer (E)-1(hydroxy), which exist in a keto form, has been synthesized. However, the spectroscopic data of (Z)-1(keto) and (E)-1(keto) were not consistent with those reported for natural schizocommunin. After reinvestigating the spectral data for natural schizocommunin, we synthesized the quinazolinone derivative (Z)-2 as a revised structure for schizocommunin. All of the spectral data of (Z)-2 were completely identical to those reported for natural schizocommunin. (Z)-2 showed moderate antiproliferative activity.
