Total synthesis of (−)-laminitol (1D-4C-methyl-myo-inositol) via microbial oxidation of toluene
摘要:
The chiral cyclohexadienediol (4), available from oxidation of toluene by Pseudomonas putida, can be converted via selective epoxidation and ring-opening to the C-methyl conduritol F (8) and thence to (-)-laminitol (2).

aminocyclitol natural products from inexpensive C2-symmetric l-tartaric acid was developed. The pivotal epoxide was used as a commonintermediate to accomplish eight diverse target molecules in six to eleven steps. Various allyl-amine-type conduramines were synthesized in a diastereoselective manner. Heck arylation was explored to construct a phenanthridone ring in a concise synthesis of (+)-lycoricidine. In
