The synthesis of ascorbic acid derivatives 7a-d is described. Starting from alkenylacetates 1a-d subjected to a hydrosilylation reaction, the resulting hydroxy chloro silanes 3a-d were obtained in high yield. The latter compounds were reacted with potassium phthalimide followed with hydrazine hydrate to give the amino silanols 5a-d. Ascorbic acid was then alkylated on its 3-hydroxy position to give 7a-d by means of a Mitsunobu reaction.

We report a new methodology for the organocatalytic diboration reaction using inexpensive, sustainable, nontoxic, commercially available halogen salts. This is an educative manuscript for the transformation of laboratory scale reactions into a sustainable approach of appeal to industry.
Enantioselective Hydroformylation of 1-Alkenes with Commercial Ph-BPE Ligand
Yu, Zhiyong,Eno, Meredith S.,Annis, Alexandra H.,Morken, James P.
supporting information, p. 3264 - 3267 (2015/07/15)
A rhodium complex, in conjunction with commercially available Ph-BPE ligand, catalyzes the branch-selective asymmetric hydroformylation of 1-alkenes and rapidly generates α-chiral aldehydes. A wide range of terminal olefins including 1-dodecene were examined, and all delivered high enantioselectivity (up to 98:2 er) as well as good branch:linear ratios (up to 15:1).
