Qulacs: a fast and versatile quantum circuit simulator for research purpose
Qulacs, a fast simulator for quantum circuits intended for research purpose, is introduced and how to use its features via examples is explained, and its performance with numerical benchmarks is demonstrated. Expand
A new method for the protection of carboxylic acids with a triisopropylsiloxymethyl group.
The reactions of various carboxylic acids with C(12)H(25)SCH(2)OTIPS in the presence of CuBr(2), Et(3)N, and molecular sieves 4A afford the corresponding triisopropylsiloxymethyl esters in good yields. Expand
Unified synthesis of tirandamycins and streptolydigins.
The comprehensive approach features the highly enantio- and diastereoselective assembly of the anti,anti,syn-stereotetrad unit which relies on a cinchona alkaloid-catalyzed asymmetric Morita-Baylis-Hillman reaction. Expand
Differentiation of germination characteristics in Scutellaria rubropunctata (Lamiaceae) associated with adaptation to rheophytic habitats in the subtropical Ryukyu Islands of Japan
This study may be the first to demonstrate the differentiation of seed germination characteristics in relation to adaptations to a rheophytic habitat and suggest an asynchronous germination which is thought to reduce the risk of disturbance in fluctuating environments. Expand
Stereoselective Construction of Entire Diastereomeric Stereotetrads Based on an Asymmetric Morita–Baylis–Hillman Reaction
A method for the enantio- and diastereoselective construction of all possible stereoisomers of a polypropionate stereotetrad having four contiguous stereogenic centers has been developed. TheExpand
